Question

Food cooking is an example of an endothermic reaction, because _____.

A. the reaction could not occur without oxygen
B. gravity is required to hold the food in the pan
C. the food cooks more quickly if it is cut up into smaller pieces
D. removing the source of heat would cause the reactions to stop

Answer 1

Food cooking is an example of an endothermic reaction, because removing the source of heat would cause the reactions to stop

Answer: Option D

Step-by-step explanation:

Cooking food is an example of endothermic or the heat-absorbing reaction where heat is absorbed by the system from the surrounding. Food is cooked by absorbing heat from the surroundings. Hence the temperature of the surrounding decreases.

Now when the source of heat is removed that would cause the reactions to stop. In an endothermic reaction an external heat is required for the reaction to proceed. Hence when the heat is removed and as the product is not that stable it is liable to stop the reaction.
