  • Which one of the following sets of phenomena would increase on raising the temperature: a. Diffusion, evaporation, compression of gases b. Evaporation, compression of gases, solubility

Which one of the following sets of phenomena would increase on raising the temperature?

(a) Diffusion, evaporation, compression of gases
(b) Evaporation, compression of gases, solubility
(c) Evaporation, diffusion, expansion of gases
(d) Evaporation, solubility, diffusion, compression of gases

Answers (1)

Ans. (c)

Sol.

Temperature is the measurement of kinetic energy of particles or molecules for any substance, so on increasing temperature their kinetic energy increases.
The process of diffusion means intermixing of molecules of two different gases, which will definitely increase on increasing temperature.
In process of evaporation liquid molecules get converted into its vapor, for which they need energy which can be supplied by increasing temperature.

Generally solubility also increases by increasing temperature.
Thermal expansion is a general phenomenon which is observed in all the matters including gases liquids or solids and they will increase their volume on increasing temperature.

Hence the correct answer is option C
