Ethyl chloride (C2H5Cl) boils at 12∘C. When liquid C2H5Cl underpressure is sprayed on a room-temperature (25∘C) surface in air,the surface is cooled considerably.Assume that the heat lost by thesurface is gained by ethyl chloride. What enthalpies must youconsider if you were to calculate the final temperature of thesurface?
Check all that apply.
The specific heat of the solid surface
The enthalpy of vaporization of C2H5Cl(l)
The specific heat of C2H5Cl(l)
The specific heat of C2H5Cl(g)
