what is the initial temperature of the tin?

Question

A sample of solid tin is heated with an electrical coil. If 46.6 Joules of energy are added to a 14.5 gram sample and the final temperature is 39.8°C, what is the initial temperature of the tin?

Answer 1

Heat energy in results in increase of of internal energy which is related to temperature change, the mass of substance and the specific heat: Q (heating in J) = mc(T_f - T_i). You need to look up the C of tin in J/g °C.

Solving for T_i = T_f - Q/mc

Good luck!
