A piece of iron of mass 2.0 kg has a heat capacity of 966 JK-1. Find: (i) heat energy needed to warm it by 15° Celsius and (ii) its specific heat capacity in S.I. unit.
(i) To find the heat energy needed to warm the iron by 15°C, we can use the formula:
Heat energy = mass × specific heat capacity × change in temperature
Given:
Mass = 2.0 kg
Change in temperature = 15°C
Since the specific heat capacity is not provided, we cannot directly calculate the heat energy. Could you please provide the specific heat capacity of iron?
(ii) The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of 1 kilogram of the substance by 1 degree Celsius. In SI units, the specific heat capacity is measured in joules per kilogram per degree Celsius (J/kg°C).
