How much heat is needed to heat a 2 kg brick from 20 ° C to 220 ° C?

The amount of heat that will be spent on heating the brick is calculated by the formula:
Q = C * m * (tк – tн), where C is the specific heat capacity of the brick (C = 750 J / (K * kg)), m is the mass of the brick (m = 2 kg), tк is the final temperature of the brick (tк = 220 ºС), tн – the initial temperature of the brick (tн = 20 ºС).
Let’s calculate the required amount of heat:
Q = C * m * (tк – tн) = 750 * 2 * (220 – 20) = 300000 J = 300 kJ.
Answer: Heating a brick requires 300 kJ of heat.
