Question

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

Answer 1

Answer:

a)250°C

gaseous

The physical state of water at 250°Cis a gaseous state. We all know that the boiling point of water is 100°C.

After attaining the temperature 100°C, the water starts converting into a gaseous state as it changes into vapours and boiling occurs. 250 °C which is much above the boiling point of water.

b)100°C

The physical state of water at 100°C means it is nothing but the boiling point temperature. The water at 100°C will be both in the liquid state as well as the gaseous state. This is because, at 100°C, the liquid state of water starts changing into its gaseous state (steam).
