Use specific heat energy

Question

The specific heat capacity of solid copper is 0.385 J/g °C.

(a) Determine the amount of heat energy that is associated with heating a 13.4-g sample of solid copper from 22.2 °C to 39.6 °C.

 J

(b) Calculate the final temperature reached when 340 J of heat is added to a 22.9-g sample of solid copper initially at 22.2 °C.

 °C

Answer 1

Hello, Natalie,

Use the equation that relates energy to temperature as a function of specific heat: q = cm(T1-T2)

The answer is negative since heat is being absorbed by the system.

I hope this helps, Bob
