Based on the thermodynamic properties provided for water, determine the energy change when the temperature of 1.25 kg of water decreased from 113 °c to 55.0 °c.

Energy change = - 303050 J

Explanation:

the heat energy Q is given by the formula

Q = m C ΔT

m = mass of water=1.25 Kg

C = specific heat of water = 4180 J/Kg °C

ΔT = change in temperature = 55-113 = - 58°C

Q = 1.25 (4180) (-58)

Q=-303050 J

Negative sign shows that the energy is released or lost.
