How to calculate the energy change in this situation

• Burning alcohol raised the temperature of 50cm of water from 16 degrees celcius to 41 degrees celcius. How much energy was released by the fuel?

You can calculate the amount of energy required to heat something using the following

equation E = m × C × T

Energy mass specific heat temperature Transferred capacity change (J) (g) (J/g°C) (°C)

50 x 4.2 x 25 = 5250J
