For this problem, we are being asked to determine the enthalpies consider if you were to calculate the final temperature of the surface

Recall that the calorimetry equation is equal to:

$\overline{){\mathbf{Q}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{\mathbf{mC}}{\mathbf{\u2206}}{\mathbf{T}}}$

where Q is the heat

m is the mass

C is the specific heat

ΔT is the change in temperature.

Ethyl chloride (C_{2}H_{5}Cl) boils at 12 ^{o}C. When liquid C_{2}H_{5}Cl under pressure is sprayed on a room-temperature (25 ^{o}C) surface in air, the surface is cooled considerably.

Assume that the heat lost by the surface is gained by ethyl chloride. What enthalpies must you consider if you were to calculate the final temperature of the surface? Check all that apply.

a) The specific heat of C_{2}H_{5}Cl(g)

b) The specific heat of the solid surface

c) The specific heat of C_{2}H_{5}Cl(l)

d) The enthalpy of vaporization of C_{2}H_{5}Cl(l)
