Vapor pressure of liquid at 25°C: will it evaporate, boil, or freeze?

[glasshut137]

[SOLVED] vapor pressure

Homework Statement

the vapor pressure of a liquid at 25 degrees celsius is 200 torr. If the pressure over the liquid is lowered to 190 torr at 25 degrees celsius the liquid will...

a)evaporate
b)boil
c)freeze

Homework Equations

The Attempt at a Solution

ok, so i think it would evaporate since the vapor pressure would decrease and therefore the decrease in pressure holding the liquid together would allow evaporation to take place. Can someone tell me if my reasoning is correct?

You are close but consider that evaporation is usually applied to liquids under isobaric conditions. What happens to a liquid when you subject it to a slight vacuum (or slightly lower)?
