Question

B. Write T for true or F for false. 1. Physical change is a permanent change.
2. Melting of ice is a chemical change. 3. Carbon dioxide does not dissolve in water.
4. In solids, the molecules are loosely packed.
5. The movement of molecules increases on cooling.​

Answer 1

Answer: All are false

1.F - Physical change can be reversed

2.F - Melting of ice forms water, and freezing water leads to the formation of ice. Therefore, it is reversible and can't be called chemical change

3.F - Carbon dioxide does dissolve in water as it is a gas and gases disperse easily in water.

4.F - The molecules are tightly packed in solids, which leads them to stay in a consistent shape, unlike the other states of matter

5.F - Movement of molecules increase on heating, not cooling.
