Four different fuels are burned to warm a beaker of water for the same length of time, using the apparatus shown. The water’s starting temperature and the temperature after heating by each fuel are measured. Which fuel gives out the greatest amount of heat energy?
- Ainitial temperature $17\,^{\circ}\text{C}$, temperature after heating $46\,^{\circ}\text{C}$
- Binitial temperature $24\,^{\circ}\text{C}$, temperature after heating $52\,^{\circ}\text{C}$
- Cinitial temperature $26\,^{\circ}\text{C}$, temperature after heating $61\,^{\circ}\text{C}$
- Dinitial temperature $30\,^{\circ}\text{C}$, temperature after heating $62\,^{\circ}\text{C}$
