Question

Which one of the following set 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

Answer 1

Answer:

Correct option is

(C)

Evaporation, diffusion, expansion of gases

As temperature increases, kinetic energy of gases increases and now molecules will move faster than earlier hence they will have high evaporation, diffusion, expansion of gases as all these properties are directly proportional to temperature.

Solubility depends on a particular reaction, if the reaction is endothermic then solubility increases otherwise it will decrease.

Answer 2

Answer:

c

Explanation:

the water evaporates up, the gases expand
