Q 2. What is the physical state of water at:
a. 250ºC
b. 100ºC
The primary state of water is liquid at room temperature. It changes to the gaseous state above . At water (liquid) can be in equilibrium with the gaseous state.
Hence, (i) At 250 physical state of water is gas. and,
(ii) At 100 physical state of water can be gas as well as liquid.
