States of Matter — CHEMISTRY STD 6 — Question

Aim : To show that matter has mass Materials Required : A spring balance, cotton thread, a small empty can, water, pebbles or sandProcedure :

1. Suspend the spring balance from a hook. The reading of the pointer should read O.
2. Take an empty can and tie it to a piece of strong cotton thread to make a suspension loop. Now suspend the can from the hook of the spring balance.
3. Note the reading of the pointer.
4. Now pour some water into the can. What do you observe ?
5. Repeat the experiment using sand or pebbles in the can. What do you observe ?
6. Note the reading of the pointer each time.

Observation :
Record your observations as follows:

1. Object
2. Initial reading of the pointer
3. Final reading of die pointer
4. Difference in the final and initial reading of the pointer.

Conclusion:
The difference between the final and the initial reading of the pointer gives the weight of the things put in the can. Thus, from above Activity, we conclude that matter has mass.
