The vapor pressure of a liquid is thepressure exerted by its vapor when the liquid and vapor states

The vapor pressure of a liquid is thepressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure, P, and temperature, T, is expressed by the Clausius-Clapeyronequation

Part A.
The instruction booklet for your pressure cooker indicates thatit’s highest setting is 12.3 psi. You know that standard atmosphericpressure is 14.7 \rm psi, so the booklet must mean12.3 psi above atmospheric pressure. Atwhat temperature will your food cook in this pressure cooker set on"high"?

Part B.
Which of the following factors affect thevapor pressure of a liquid?
Choose all that apply.

a) amount of liquid
b) atmospheric pressure
d) surface area of the liquid
e) type of liquid
f) temperature

Concepts and reason
Vapor pressure is the pressure exerted by the vapor in equilibrium with its condensed phase (liquid or solid) in a closed system at the given temperature.

Fundamentals
The relationship between temperature and pressure is expressed with the help of the Clausius – Clapeyron equation:
