Step-by-step explanation:

The boiling point of a substance is 293°C.

The boiling point is the temperature at which the vapor pressure of a liquid becomes equal to the atmospheric pressure.

So, at the boiling point:

The vapor pressure =atmospheric pressure = 1 atm.

To get the vapor pressure of the substance at 220°C is definitely less than 1 atm.

Since, as the temperature increases, the vapor pressure of the liquid increases.
