Question

The physical state of water at 373 K is _____________ a) Solid b) liquid c) vapour d) plasma

Answer 1

Dear Student,

◆ Answer -

The physical state of water at 373 K is vapour.

● Explanation -

• 373 K = 373-273 ℃ = 100 ℃
• As we know, 100 ℃ is the boiling point of water.
• At 100 ℃ water boils gets converted into vapour (gas) form.
• At this temperature, some part of water may still be in liquid form.

Thanks dear. Hope this helps you...

Answer 2

Answer:

The physical state of water at 373 K is both liquid and vapour.

Explanation:

373K is equivalent to 100 degrees Celsius (373-273). At 100 °C water begins to boil as it is the boiling point of water. At this temperature water changes from its liquid state to the gaseous state.

Liquid water now converts to water vapour and the vapour pressure exerted is the same as the atmospheric pressure. As a result the vapour phase and liquid phase are in equilibrium and its physical state is that of liquid-vapour.
