Hanif thought that more heat energy has been given out in his reaction and noor thought that both reactions gave out same amount of heat. Whose idea is correct and why?

This question is incomplete but the missing part is in the document attached

Noor's idea is correct

Explanation:

Noor's idea is correct. This is because the temperature rise in the two experiments are the same and can be calculated as follow

Hanif's experiment: 45 - 21 = 24 °C

Noor's experiment: 42 - 18 = 24 °C

Thus, the correct idea is both reactions gave out same amount of heat
