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

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
