Which of the following sets of phenomena would increase on raising the temperature?
Which of the following sets of phenomena would increase on raising the temperature?
The correct option is C Evaporation, diffusion, expansion of gases
Diffusion is defined as the movement of molecules of a substance through a semipermeable membrane from an area of higher concentration to an area of lower concentration.
Evaporation is a process by which the molecules of a liquid turn into vapour.
Solubility is the amount of solute that dissolves in a solvent.
Compression of gases means how much gas can be compressed when pressure is applied.
The explanation for incorrect options
a. Diffusion is directly proportional to temperature, Evaporation is directly proportional to temperature whereas Compression is inversely related to temperature. Hence, this option is incorrect.
b. Evaporation is directly proportional to temperature, Compression of gas is inversely proportional to temperature and Solubility is directly proportional to temperature. Hence, this option is incorrect.
d. Evaporation, solubility and diffusion are directly proportional to temperature, whereas compression of gases is inversely proportional to temperature. Hence, this option is incorrect.
The explanation for correct option
c. Evaporation, diffusion, and expansion of gases all are directly proportional to temperature hence will increase on increasing the temperature. Hence, this option is correct.
Hence the correct option is C.
