Question

The metal case of the stove gets hot when the fire is lit. Here is some information about the stove

Answer 1

The energy required to raise the temperature of the metal case from 20°C to 70°C is 2550KJ. Details about energy can be found below.

How to calculate energy?

The energy required to raise the temperature of a substance can be calculated using the following formula:

Q = m × c × ∆T

Where;

• Q = quantity of heat energy
• m = mass
• c = specific heat capacity
• ∆T = change in temperature

Q = 100 × 510 × (70 - 20)

Q = 2,550,000J

Q = 2550KJ

Therefore, the energy required to raise the temperature of the metal case from 20°C to 70°C is 2550KJ.
