Question

at a give temperature one liquid has a vapour pressure of 240. torr and another Measure 420. torr which liquid property has the lower boiling point which probably has the lower heat of vaporization?

Answer 1

The vapor pressure of a substance is the pressure at which its gas phase is in equilibrium with its condensed phases (liquid or solid)

The higher the vapor pressure of a liquid at a given temperature, the higher the volatility and the lower the normal boiling point of the liquid.

From the given vapor pressures :

420torr has a higher vapor pressure hence it has a lower boiling point.

240 torr has a higher boiling point.

Answer 2

Answer:

The vapor pressure of a substance is the pressure at which its gas phase is in equilibrium with its condensed phases (liquid or solid)

The higher the vapor pressure of a liquid at a given temperature, the higher the volatility and the lower the normal boiling point of the liquid.

From the given vapor pressures :

420torr has a higher vapor pressure hence it has a lower boiling point.

240 torr has a higher boiling point.
