Energy: Specific Heat Capacity

Question 1

What is specific heat capacity?

Answer 1

Specific heat capacity is **the amount of energy required to raise the temperature of 1kg of a substance by 1^oC

Question 2

Calculate the energy required to increase the temperature of 2kg of water from 20^oC to 100^oC.
The specific heat capacity of water is 4200J/kg^oC.

Answer 2

2 x 4200 x 80 = change in thermal energy
= 672 kJ / 672, 000 J
