Let's suppose the difference is ΔT = -3 K and m is 5 kg. Step 3: Just put the values in specific heat equationas c = Q / (m x ΔT). In this example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/ (kg•K). This is the typical heat capacity of water and it can be calculated by specific heat calculator as well in one go.
