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

When two materials with different temperatures come in contact the heat flow happens from
warmer material to cooler material until the temperature of both objects is the same. That is to say
the total heat or energy is conserved and not lost during the process.
Therefore
qhot + qcold = 0
When the above equation is rea
anged as
qcold = - qhot
it indicates that the heat...
