Question

1. A 200.0 g copper block absorbs 2.34 × 10^3 J of heat to raise its temperature by 30.0 K. What is the specific heat of copper? Show your work
2. A 500.0 g metal block absorbs 3.25 × 10^3 J of heat to raise its temperature by 50.0 K. What is the substance? Show your work.

Answer 1

Specific heat is the amount of heat per unit mass required to raise the temperature by 1 degree Celsius or Kelvin.
\[Q = c m \Delta T\]
200.0 g (0.20 kg) of Cu required 2.34 * 10^3 J to raise its temerature by 30.0 K.
2.34 * 10^3 J / 0.20 / 50.0 = ?
