Question

Give reasons for the following:
(i) Condensation of a water-vapour is a physical change.
​

Answer 1

Answer:

Condensation is a physical change. In condensation, a gas turns into a liquid. The molecules of the gas do not change when they turn into the liquid.

Answer 2

Answer:

Yes because the water can also be converted in steam by boiling and into ice by freezing. Hence the process is reversible .....therefore it is a physical change.
