Which one of the following sets of phenomena would increase on raising the temperature?a. Diffusion, evaporation, compression of gasesb. Evaporation, compression of gases, solubilityc. Evaporation, Diffusion, Expansion of gasesd. Evaporation, solubility, diffusion, compressibility of gases

To determine which set of phenomena would increase on raising the temperature, let's analyze each option:

a. Diffusion, evaporation, compression of gases:

• Diffusion is the process by which particles spread out from an area of high concentration to an area of low concentration. Increasing the temperature would increase the kinetic energy of the particles, leading to faster diffusion.
• Evaporation is the process by which a liquid turns into a gas. Raising the temperature would increase the average kinetic energy of the liquid particles, making them more likely to escape into the gas phase.
• Compression of gases refers to the reduction in volume of a gas. Increasing the temperature of a gas would cause the gas particles to move faster and collide more frequently, resulting in increased pressure and compression.

b. Evaporation, compression of gases, solubility:

• We have already discussed the effects of raising the temperature on evaporation and compression of gases in option a.
• Solubility refers to the ability of a substance to dissolve in a solvent. In general, raising the temperature increases the solubility of most solid solutes in liquid solvents. However, the effect of temperature on solubility can vary depending on the specific solute and solvent.

c. Evaporation, diffusion, expansion of gases:

• We have already discussed the effects of raising the temperature on evaporation and diffusion in option a.
• Expansion of gases refers to the increase in volume of a gas. Increasing the temperature of a gas would cause the gas particles to move faster and collide more frequently, resulting in increased volume and expansion.

d. Evaporation, solubility, diffusion, compressibility of gases:

• We have already discussed the effects of raising the temperature on evaporation, diffusion, and compressibility of gases in options a and b.
• Solubility refers to the ability of a substance to dissolve in a solvent. As mentioned earlier, raising the temperature generally increases the solubility of most solid solutes in liquid solvents.

Based on the analysis, the correct answer is option c: Evaporation, diffusion, expansion of gases.
