Question

Units of specific heat capacity.​

Answer 1

☆ Units of specific Heat Capacity :

➣ The S.I. unit of specific heat capacity is joule per kilogram per kelvin (or J kg⁻¹ K⁻¹) or joule per kilogram per degree celsius (or J kg⁻¹ °C⁻¹).

➣ The other units of specific heat capacity are cal g⁻¹ °C⁻¹ and kcal kg⁻¹ °C⁻¹. These units are related as :

➸ 1 cal g⁻¹ °C⁻¹ = 1 kcal kg⁻¹ K⁻¹

➸ 4.2 ༝ 10³ J kg⁻¹ K⁻¹

✿ Note :

• If specific heat capacity of copper is 0.4 J g⁻¹ K⁻¹, it means that the heat energy required to raise the temperature of 1 g of copper by 1 K (or 1 °C) is 0.4 J.
