Question

the solubility of solids in water___:
a. is independent of the temperature
b. increases with increasing temperature
c. decreases with increasing temperature
d. solids are not soluble in water
e. doesnt exist

Explanation:

To solve this, we recall the general trend of solubility of most solids in water. For the majority of solid solutes, as temperature increases, the kinetic energy of solvent and solute particles increases, allowing more solute to dissolve (though there are exceptions, but the question is about the general case). Option a is wrong as temperature affects solubility. Option c is true for some exceptions (like gases or a few solids), but not the general case for solids. Option d is wrong (e.g., salt, sugar are soluble in water). Option e is wrong as solubility of solids in water does exist. So the correct answer is the one stating the general trend for most solids.

Answer:

b. increases with increasing temperature
