Specific HeatEasyQuestion 30841

Question

Specific heat capacity is the heat required to raise temperature of:
  1. A
    1 g by 100°C
  2. B
    1 kg by 1°C
    Correct
  3. C
    1 mol by 1 K
  4. D
    1 g by 1 K only

Correct answer

1 kg by 1°C

Explanation

Specific heat c = Q/(mΔT), so 1 J/kg·K means 1 J raises 1 kg by 1°C.
