Choose the correct option/options:
The correct options are
A The boiling point of a liquid increases with the increase in pressure.
C The boiling point of a liquid increases by the addition of impurities to it.
The boiling point of a liquid increases with the increase in pressure and decreases with the decrease in pressure. ie., the boiling point increases with increased pressure up to the critical point, where the gas and liquid properties become identical. The boiling point cannot be increased beyond the critical point.
The boiling point of a liquid increases by the addition of impurities to it. ie., adding impurities to a solution, in most cases, increases the boiling point of the solution. Once this occurs, it takes a greater amount of heat to cause the same amount of impure solution to vaporize as it would take to cause a pure solution to vaporize, thus raising the solution's overall boiling point.
Hence, the correct options are A and C.
