Since the presence of a solute lowers the vapor pressure more heat energy is required for the liquid to change to a gas.
(the presence of a solute; lowers; the vapor pressure) (more heat energy; is required; for the liquid to change to a gas; T:Since the presence of a solute lowers the vapor pressure) (the liquid; to change; to a gas)
the presence of a solute more heat energy the liquid
lowers is required to change
the vapor pressure
for the liquid to change to a gas T:Since the presence of a solute lowers the vapor pressure
to a gas
