# What was the heat lost to the surroundings if #"11.3 g"# of diamond is cooled from #38.7^@ "C"# to #21.3^@ "C"#?

Well, if ever you're lucky enough to get this much diamond... the specific heat capacity of diamond is available here.

Thus, using the equation for heat transfer at constant pressure:

where:

So,

Since the temperature dropped, heat transferred out of diamond. To account for the sign...
