Lawson · Answer 1

In order to calculate the heat absorbed by the water, we require the specific heat capacity of water. This is 4.18 J/g. Now, we use the formula:

Energy = mass * specific heat capacity * change in temperature

Q = mcΔT

Q = 250 * 4.18 * (100 - 15)

Q = 88,825

The energy absorbed by the water is 88.8 kilojoules
