Question

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​

Answer 1

(c) Evaporation, diffusion and expansion of gases

Explanation:

• Evaporation is a surface phenomena which increases its phenomenon rate with the temperature, it is directly proportional to the temperature of its surroundings.
• Diffusion rate also increases as the molecules get apart from each other during heating.
• Expansion of gases also occurs because the molecules move away from each other leading to the expansion of the object (it can be any kind of matter).
