a liquid with weak intermolecular forces and a high temperature

Explanation:

According to encyclopedia Britannica, "Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid."

This implies that the vapour pressure of a liquid tends to increase as the temperature of the liquid increases. Recall that vapour pressure also depends on the magnitude of intermolecular forces. The greater the magnitude of intermolecular forces, the lower the vapour pressure hence water has very much higher vapour pressure than ethane.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
