Activity 8.4: Let us measure
- Take a glass tumbler half-filed with water containing a few ice cubes. Cover it with a small steel plate. Weigh it on a digital weighing balance.
- Observe the reading on the balance and record the weight after every fie minutes.
- Continue observing for 30 minutes. Record your observations in Table 8.2.
Question 1.
Predict what will happen to the mass of cold water kept on the digital weighing balance. Will it increase or decrease or remain the same? Class 6
Answer:
It will increase. (But students must give their prediction)
The mass of the cold water kept on the digital weighing balance will increase.
Table 8.2: Measurement of mass in condensation experiment using a digital weighing balance
Answer:
| Time | Mass of water |
| 0 min | 50.0 g |
| 5 min | 50.1 g |
| 10 min | 50.2 g |
| 15 min | 50.2 g |
| 20 min | 50.3 g |
| 25 min | 50.4 g |
| 30 min | 50.4 g |
