Question
Which of the properties of air can be proved from the following picture?
- Air occupies space.
- Air has mass.
- Air has volume.
- Air exerts pressure.
Hint:
When an empty glass is upside down in a basin of water. The water is unable to enter the glass because air is occupying the space in the glass because of the presence of air inside it as air applies pressure on the air present inside so as to replace it. But the air present inside the glass applies opposite force on the water as it tries to escape through the only opening present which is surrounded by water.
The correct answer is: Air occupies space.
Air occupies space can be proved from the given picture.

John performed one experiment. Find out the composition of air. He took the test tube fitted with a rubber cork. Then he poured some fresh lime water into it. Then he fitted the two long-bent tube through the two holes of rubber cork. He blew the air by an air pump through the long tube. The lime water present inside turns into a milky solution. This shows that the air contains
