Question

On increasing temperature, which of the following decreases?

Vapour pressure of liquid

Viscosity of liquid

Kinetic energy of gas

Rate of evaporation of liquid
​

Answer 1

Answer:

Molarity changes with thetemperature. With increase in temperature, volume will increase & then molarity will decrease.

Answer 2

Answer:

option A

Explanation:

vapour pressure of liquid...

because,

Surface tension, viscosity and density will decrease with increase in temperature except for vapour pressure.

Vapour pressure will increase with increase in temperature.

With increase in temperature, kinetic energy of liquid molecules increases. This increases the number of molecules that change phase from liquid to gas. It increases vapour pressure.
