C. equal to​


Sagot :

Answer:

C. equal to

Explanation:

The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil. Moreover, if pressure increases liquid temperature increases, so evaporation rate also increases. When vapor pressure reaches atmospheric pressure, boiling occurs.
