Alcohol has a higher vapor pressure than water at room temperature. This is because the intermolecular forces between alcohol molecules are weaker than those between water molecules. The weaker intermolecular forces allow alcohol molecules to escape from the liquid more easily, resulting in a higher vapor pressure.

The vapor pressure of a liquid is a measure of the tendency of its molecules to escape from the liquid and enter the gas phase. The higher the vapor pressure, the more volatile the liquid.
