Question
A piece of iron of mass 2.0 kg has a heat capacity of 966 J K-1. Find its specific heat capacity in S.I unit.

Solution
Mass of iron m = 2.0 kg
Thermal Heat Capacity c' = 966 J/°C
Rise in temperature T = 15°C
We know that specific heat capacity is = `"heat capacity"/ "mass of substance"`
So specific heat capacity is = `966 / 2`
= 483 J kg-1 K-1
