RP 1 - Specific Heat Capacity GCSE Exam Questions (B.S.G)
Stels [109]

When the temperature of 0.50 kg of water decreases by 22 °C, the energy transferred to the surroundings from the water is -46.2 kJ.

A sample of 0.50 kg of water boils (reaches 100 °C). After a while, its temperature decreases by 22 °C.

We can calculate the energy transferred to the surroundings from the water in the form of heat (Q) using the following expression.

Q = c \times m \times \Delta T = \frac{4200J}{kg.\° C}  \times 0.50kg \times (-22\° C) \times \frac{1kJ}{1000J} = -46.2 kJ

where,

  • c: specific heat capacity of water
  • m: mass of water
  • ΔT: change in the temperature

When the temperature of 0.50 kg of water decreases by 22 °C, the energy transferred to the surroundings from the water is -46.2 kJ.
