What causes evaporation in a liquid?

An increase in the volume of the liquid.

Heating of the liquid, leading to an increase in molecular kinetic energy.

The presence of impurities in the liquid.

At what point does vapour pressure reach its maximum value?

When there are no liquid molecules left in the container.

When the rate of evaporation equals the rate of condensation.

When the temperature of the liquid is at its lowest point.

When the volume of the liquid is at its maximum.

What is vapour pressure?

The pressure exerted by a liquid at its boiling point.

The pressure exerted by a gas in a closed system.

The pressure exerted by the vapour of a liquid in equilibrium with its condensed phases.

The pressure exerted by a solid in a closed container.

What is the boiling point of a liquid defined as?

The temperature at which the liquid's vapour pressure equals the atmospheric pressure.

The temperature at which the liquid starts freezing.

Vapour pressure is independent of temperature.

Vapour pressure increases with increasing temperature.

Temperature has no impact on vapour pressure.

Which type of liquid is likely to have a higher vapour pressure at a particular temperature: water or acetone?

They have the same vapour pressure.

It depends on the volume of the liquid.

What is the Heat of Vaporization?

The heat required to freeze a liquid.

The heat required to raise the temperature of a liquid by one degree Celsius.

The heat required to convert one mole of liquid into the gaseous state at the boiling point.

The heat required to condense a gas.

What does Raoult's law describe in relation to vapour pressure?

It describes the relationship between temperature and vapour pressure.

It explains the effect of impurities on vapour pressure.

It relates the total vapour pressure to the mole fraction of components in a solution.

It defines the relationship between vapour pressure and volume.

How is the total vapour pressure above a solution affected by the mole fraction of a component?
