Which phenomena would increase on raising the temperature
Which one of the following sets of phenomena would increase on raising the temperature?
- Diffusion, evaporation, compression of gases
- Evaporation, compression of gases, solubility
- Evaporation, diffusion, expansion of gases
- Evaporation, solubility, diffusion, compression of gases
Answer
Evaporation, diffusion and expansion of gases increase on raising the temperature. Evaporation rate increases because on increasing temperature, kinetic energy of molecules increases, so the molecules present at the surface of the liquid leave the surface quickly and go into the vapour state.
Diffusion and expansion of gases also increase as the molecules move more rapidly and try to occupy more space.
The correct option is C.
