1.	Consider an experiment given below.Take a tin can with a lid. Fill it approximately half with water. Heat it till the water boils. Remove from heat. Now, pour fresh water over the can. What happens to the shape of the can?1. No change in the structure of the can2. Can gets distorted3. Can will expand4. Can will burst
Answer» Correct Answer - Option 2 : Can gets distorted The correct answer is Can gets distorted. It is an Air exerts pressure type activity. Take a tin can with a lid. Fill it approximately half with water. Heat it till the water boils. Remove from heat. Now, pour fresh water over the can. The shape of the can gets distorted. Inference: As water is poured over the can, some steam in the can condenses into water, reducing the amount of air inside. The pressure of the air inside the can decreases than the pressure exerted by the air from outside the can. As a result, the can gets compressed. Fact about Air: Air has weight. The weight of air presses our bodies all the time. This weight of air acting on a surface causes air pressure. Some daily life experiences that show that air exerts pressure: You find it easier to row the boat when the wind is blowing behind you. The wind coming from the back helps in flying the kite. When we suck from the straw, the liquid rises in it. The medicine enters the syringe when a piston is pushed out.
