A 1.5kg piece of copper is set out in the sun. Its temperature rises from

34°C to 48°C and the specific heat is 387J/(kg°C). What is the heat energy
gained by the metal?

Answer:

8.13 kJ

Step-by-step explanation:

Q = mCT where Q is the energy (in Joules, here), m is the mass (kg, here) C is the specific heat, and T is the temperature (C).

Q = mCT

Q = (1.5kg)*((387J/(kg*C))*(14C)

Q = 8127 J, or 8.13 kJ with 3 sig figs.
