Question

4. Why is cooking an endothermic process?

A) Uncooked food contains more chemical energy than cooked food.
B) Energy is continuously added for the chemical reactions to take place.
C) The chemical reactions involved in burning fuels release energy

Answer 1

Hi there!

The answer that best fits is B: Energy is continuously added for the chemical reactions to take place.

Step-by-step explanation:

Endothermic means energy GOING IN not releasing.

Answer 2

Answer: The correct answer is Option B.

Step-by-step explanation:

Endothermic reactions are defined as the reactions in which energy is absorbed by the system. The total enthalpy of the reaction comes out to be positive.

Exothermic reactions are defined as the reactions in which energy is released by the system. The total enthalpy of the reaction comes out to be negative.

Cooking is a type of endothermic reaction because in this process, energy is given to the uncooked food continuously. Energy is getting absorbed by the food for the chemical reactions to take place.

Thus, the correct answer is Option B.
