Question

iv) Calculate the amount of heat required to raise the temperature of 1 kg of iron through 10°C​

Answer 1

Answer:

The amount of heat required to raise the temperature of a substance is determined by the following equation:

Heat (J) = mass of substance (g) x heat capacity of substance (J/g.K) x the change in temperature (K).

In this case the heat required = 1000 x 0.45 x 10 = 4500 J or 4.5 kJ
