Write an experiment to prove any 1 property of air (i.e. Air
occupies space/ Air has mass or volume/ Air exerts pressure-as
performed in class), under the following bullets AIM, MATERIALS REQUIRED, PROCEDURE, OBSERVATION AND INFERANCE
Answers
Answer:
Explanation:
Solution :
(a) Experiment - To show air occupies space
Procedure - A glass bowl is half filled with water. An empty glass tumbler is inverted inside the bowl.
When the tumbler is tilted, bubbles are seen in water.
Observation - The air was occupying space inside the tumbler, and on tilting air is displaced and bubbles come out because of that.
Conclusion - Air occupies space.
(b) Experiment - To show air has mass
Procedure - An inflated balloon is placed on one side of a simple scale, and the scale tilts towards one side.
Observation - The balloon has mass which makes the scale tilt.
Conclusion - Air has mass.
(c) Experiment - To show air exerts pressure.
Procedure - An open can is filled with water and heated. On the formation of steam, the cap is placed tightly such that steam is inside the can.
Observation - The steam condenses and the pressure inside reduces as the steam reduces. The air outside the can exerts pressure and makes the can crumple.
Conclusion - Air exerts pressure.
(d) Experiment - To show air is highly compressible.
Procedure - A leak proof syringe which is empty and filled with air is pushed towards the end.
Observation - The piston of the syringe is moved inwards, which implies the air inside the syringe is compressible.
Conclusion - Air is highly compressible.
