Question

2. What is the physical state of
water at:
a. 250°C b. 100°C ?​

Answer 1

a.At 250°C the state of water is gaseous.

b.At 100°C the state of water is both gaseous and water.

Hope it helps you...✌️

Answer 2

Explanation:

a): Physical state of water at 250°C is gaseous state because the boiling point of water is 100°C. Therefore at a temperature higher than its boiling point. It exists as gas.

(b): At 100°C both liquid and gaseous states are present. These are in a state of equilibrium. So at 100°C both liquid water and vapour are present.
