Generally, we feel air doesn’t have any weight since it is not visible and just felt.

Are you wondering about, ‘Does air has mass?’!!

If you are interested, we can clear your curiosity about ‘air weight’ through this scientific experiment, i.e., ‘Balloon Balance Experiment.’ Here we go!

Hypothesis: We will prove that air has weight / mass by building a balance scale and performing an air weight experiment.

Check out the concise list of supplies…

Step-1: Build a balance using a ruler and strings! Take a ruler of your chosen material and give it a knot using a piece of string but precisely in the center. Make sure the string is strong enough to hold and balance the ruler scale in place.

Step-2: Now, bring the balance over your work table and attach the other free end of the string to support on the top. If you have a readymade balance available readily at home, then you can also use it.

Step-3: Then, pick the two balloons and blow them up. But you need to blow the two balloons in equal size.

Step-4: After checking, give the balloons a knot at the mouth of them using an equal length piece of string.

Step-5: It is time to fix the balloons on either side ends of the ruler, leaving 3-4 inches of space from the end of the scale. Fix the balloons to the ruler using the other free end of the string attached to the balloon.

As we are taking equal length strings to both the balloons to secure them, we must mostly observe the balloons at the same height even after tying them to the ruler. Finally, you need to check whether the balloons are at equal height from the ruler.

Step-6: At this stage, leave the balance attached with equal-sized and inflated balloons freely. That means let the balance adjust itself, and then you check, both the balloons remain at the same height as the ruler.

It shows that air inside both the balloons has equal mass and remains at the same height when left on balance freely.

Step-7: In step-7, we are going to prove that air has mass! To prove this, pick any sharp object and poke any of the two balloons.

Immediately, you can observe the balance goes down on the side where there is an inflated balloon and the side consisting of deflated balloon goes up.

Just like a see-saw, you can observe the actions of balance when you deflate one of the balloons using a sharp object.

You can alter the experiment with varying mass of balloons to check the results.

According to scientists, air is a type of matter that has mass and occupies space.

Let us prove with our experiment that air has mass and takes up space. In the balloon balance experiment, we are blowing up balloons. When blow-up balloons, the air is entering inside them and making the balloons expand. So, this shows that the air occupies space which eventually proves that it has weight.

And when we tie the balloons to the scale with measurements and deflate one of them, the balance tilts i.e., the side attached to the inflated balloon will be on the lower side, and the side with deflated one goes upwards.

The deflated balloon loses its weight. And because of weight, the inflated balloon goes down, and the deflated one goes up on the scale. Using this, we can prove that air takes up space and has mass.

When we blow up the balloon, the air inside the balloon is under high pressure. Because the amount of air inside the balloon is compressed within a certain amount of space available inside the balloon.

So when we blast it using a sharp object, the balloon’s skin moves away from the blast’s point, allowing the air to come outside. The compressed air comes out of the balloon when it blasts because it weighs more than the surrounding air weight. This shows that air has weight.

A deflated balloon exhibits the weight of the (deflated) balloon and not the air.

Air has no weight when it is free to move from one place to another, but it contains weight when it is filled inside any container because the air inside a container compresses by the walls of balloons, which gives weight to the air inside the balloon.

1) Try out many inflated balloons tied to the ruler scale on either side and perform the same experiment. Check whether there are the same final results or not!

2) Replace the deflated balloon with another inflated balloon and check what exactly happens.

3) Take many inflated balloons and tie them to the string side by side on either side of the scale. And check the results by blasting the balloons on one side at a time and one by one.

4) Try different-sized balloons and check what happens after the experiment.

Galileo, a great scientist who discovered that ‘Air has Mass,’ but he could not prove his statements through scientific reasons adequately. And hence his remarkable discovery on-air weight became colder surrounding with a lot of controversies.

Later, Torricelli put his efforts on the same concept and surmised that air is less dense and exhibits less pressure on the hilly areas. But he just only explained the theory instead of proving it scientifically.

And finally, the scientist Blaise Pascal proved that air weights with proper explanations.

As we already learned that compressed air exhibits weight more than the surrounding air moving freely outside through Balloon Balance Air has Weight Experiment. Let us see how much weight it reveals.

Compressed air weighs more than atmospheric air, and hence a certain amount of compressed air weighs more than the same amount of regular air. I.e., The weight of one cubic foot of air is 0.0807 pounds at 14.7 psi. If we compress the compressed air to 1000 psi, then the air weight per cubic foot is beyond 5 pounds. In this way, compressed air weight is calculated based on the pressure it is experiencing.

The production system of organic agricultural production is aimed at obtaining food of the highest nutrition and sensory quality through sustainable and environment friendly production methods.

This is achieved through the optimal use of available local resources and without the application of synthetic chemical products, seeking at all times a lasting agricultural development over time, without forgetting that the exploitation must be an economically viable project.

The organic farming method establishes a methodology to maintain production levels that allow the farm to last over time and in a more sustainable environment. The production system has an important strategic and social interest

We usually talk about organic farming when we refer to organic agricultural production, but it's important to remember that organic agricultural production is a more general concept and therefore includes many more terms than organic farming.

We could say that organic farming is only a part of organic agricultural production.

One of the main objectives of organic agricultural production is to ensure an adequate level of soil and crop fertility, with the fundamental objective of achieving a product of high nutrition, sanitary and organoleptic quality and with optimal production levels.

To achieve this fertility, work will be done by establishing cycles of organic matter and mineral nutrients, as well as other by-products generated by the activity itself, as closed as possible and using renewable resources.

Providing crops and livestock with adequate living and well-being conditions in such a way that they allow them to develop as naturally as possible and that allow them to obtain satisfactory productive yields is another of the fundamental objectives of organic agricultural production, as well as favoring the biological cycles of the different organisms in the ecosystem and increase the biodiversity of the environment through alternative cultivation of forage and leguminous species and the empowerment of the marginal areas of crop fields and pasture areas.

It is important to find species that are more adapted to local conditions in order to improve the integration of crops and herds.

A key point of ecological agricultural production is to avoid any form ofcontamination or loss of product quality due to techniques used in production processes or handling of agri-food products.

It will be important to combat the proliferation of pests, diseases and the appearance of weeds, but it will also be important to choose suitable species and varieties, and the crop rotation, in order to improve the health of crops and livestock.

The goal of ecological agricultural production is to achieve food production in sufficient quantity to satisfy the income and working conditions of farmers and ranchers, thus maximizing the social impact of the agricultural system and the link between producers, manufacturers, businesses, and final consumers.

Genetically modified organisms are not allowed in organic agriculture.

Ecological agricultural production is more than replacing synthetic chemical products with natural products. The production system is completely different from the conventional one because of the use of eco-friendly management strategies and techniques that promote and favor the healthy development of the environment in all its areas.

Nowadays and more, Ecological agricultural production is configured, in a new productive system, which values concepts that have fallen into oblivion.

The fight for the rural world, the influence of food on health, the defense of animal welfare, and maintaining rich and fertile soil are some of the examples of caring for the environment.

The production of products from organic raw materials and organic farming are what make up the organic foods. In this way, we can find certified organic fruit and vegetables, eggs, milk and meat, and all kinds of processed foods such as bread, cheese, jams, fruit juices, sausages and more, in the conventional market.
