A student carried out an experiment to measure the energy released when a fuel is burned. The temperature of the water in the calorimeter increased by 28.5∘C28.5^{\circ}\text{C}28.5∘C.
The heat energy transferred to the water can be calculated using the equation:
heat energy (J)=420×temperature rise \text{heat energy (J)} = 420 \times \text{temperature rise} heat energy (J)=420×temperature riseCalculate the heat energy transferred to the water in joules.
