Observa on: You will observe that the balloon that is pricked bursts and the meter scale lts towards the
infl ated balloon.
Conclusion: This happens because of the mass of air present in the balloon. The balloon which contains
air is heavier than the bursted balloon. This confi rms that ma er, here air, has mass.

Activity 3.4

Aim: To show that ma er has mass
Materials required: A can, some water, a spring balance, a thread

Procedure
• Suspend a spring balance from a hook. Make sure that the reading of the
pointer should read 0.

• Tie an empty can to a strong co on thread to form a suspension loop. Suspend
the can from the hook of the spring balance.
• Note the reading of the pointer.
• Now fi ll the can with some water. empty can

Observa on: The spring balance with the can having water shows more reading. water

Conclusion: This shows that ma er, here water, has mass.
