A sample of an unknown substance has mass of 89.5 g. If 345.2 J of heat are required to heat the substance from 285 K to 305 K, what is the specific heat of the substance?

Answer 1

Q = m c #Delta#T
Rearrange to c = Q / (m #Delta#T)

Q = 345.2J m = 89.5 g #Delta#T = (305-285)= 20
So c = 345.2 / (89.5 x 20) c = 0.193 #J g^-1 K^-1#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
