# Problem: Ethyl chloride (C2H5Cl) boils at 12 oC. When liquid C2H5Cl under pressure is sprayed on a room-temperature (25 oC) 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 C2H5Cl(g)b) The specific heat of the solid surfacec) The specific heat of C2H5Cl(l)d) The enthalpy of vaporization of C2H5Cl(l)

###### FREE Expert Solution

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:

where Q is the heat

m is the mass

C is the specific heat

ΔT is the change in temperature.

###### Problem Details

Ethyl chloride (C2H5Cl) boils at 12 oC. When liquid C2H5Cl under pressure is sprayed on a room-temperature (25 oC) 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 C2H5Cl(g)

b) The specific heat of the solid surface

c) The specific heat of C2H5Cl(l)

d) The enthalpy of vaporization of C2H5Cl(l)
