From the graph we could see
that
The vapor pressure of water at 80 degrees is approximately 360 torr
b) Average kinetic energy of molecules increases so more are able to overcome the intermolecular forces in liquid state.
c) At 20 degrees Celsius we could see from the graph that di-ethyl ether exerts more vapor pressure, hence it evaporates quickly.
d) we could see from the graph that at 450 torr , temperature is approximately 85 degrees celsius.

The vapor pressure of a liquid is the pressure 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-Clapeyron equation. lnP2P1=ΔHvapR(1T1−1T2) where P1 and P2 are the vapor pressures at the absolute temperatures T1 and T2, respectively, ΔHvap is the heat of vaporization of the substance in joules per mole, and R is the ideal gas constant, which is equal to 8.3145 J/(mol⋅K)....
