A) Which statement explains the relationship between the temperature and
vapor pressure of a liquid? (1 point)
The higher the temperature, the less molecules will vaporize, resulting in a
lower vapor pressure.
The higher the temperature, the less molecules will vaporize, resulting in a
greater vapor pressure.
The higher the temperature, the more molecules will vaporize, resulting in a
lower vapor pressure.
