A sample of solid sulfur is heated with an electrical coil. If 105 joules of energy is added to a 12.4 gram sample initially at 24.4°C, what is the final temperature of the sulfur?
First you need to make sure that this is not in the range of the melting point for S. I checked and the m.p. is abou 115 C.
q = mass S x specific heat S x (Tfinal-Tintial).
You need the specific heat S. Substitute and solve for Tfinal.
