Question

Which of the following sets of phenomena would increase with increase in temperature?

• A. Diffusion, evaporation, compression of gases
• B. Evaporation, compression of gases, solubility
• C. Evaporation, diffusion, expansion of gases
• D. evaporation, diffusion, compression of gas

Answer 1

The correct option is C

Evaporation, diffusion, expansion of gases

The explanation for correct option:

• On increasing temperature the rate of evaporation also increases, the kinetic energy of gases increases, and now molecules will move faster than earlier and hence will have high evaporation.
• Diffusion, and expansion of gases as all these properties are directly proportional to temperature.
• While solubility depends on a particular reaction if the reaction is endothermic then solubility increases.

The explanation for incorrect option:

Option A:

• Evaporation, and diffusion increase with an increase in temperature while expansion of gases increases with an increase in temperature.

Option B:

• Evaporation and solubility increase with an increase in temperature while in compression of gas the temperature is a measure of internal energy.
• When a gas is compressed temperature increases because the temperature and volume of a gas are inversely proportional to each other according to gas laws.

Option D:

• Evaporation, and diffusion increase with an increase in temperature.
• When a gas is compressed temperature increases because the temperature and volume of a gas are inversely proportional to each other according to gas laws.

Therefore option C is the correct option.
