Answer:
It is observed that H2 gas gives out 286kJ/m, Methane gives out 802.3kJ/m and hexane gives out 4163kJ/m of heat. They are all exergonic or exothermic reaction but have different values of heat given out. The amount of carbon atom present, is what determines the heat given out, as higher carbon compound like Hexane gave out more heat than Methane and Hydrogen gas have out the least.
Explanation:
0s to 15s: constant speed/zero acceleration
15s to 40s: constant gradient, therefore constant deceleration
Factor that can be controlled changed or measured in an experiment.
