According to law of thermodynamics, energy can neither be created nor can be destroyed. It can be converted from one from one form to another.
Hence, the food that we eat is a source of energy. The chemical energy stored in food, is utilized for various function of body such as breathing, walking, talking, etc. Now, if you body does not have chemical energy, if will not be able to perform various task, which are essential for living.
Due to this, <span>absence of chemical energy in the body, can </span>will eventually lead to death.

Explanation:
The zeros in 500 aren’t in the middle of 2 non number nor does it have a decimal in the number
Answer:
b. Heat flows from the surroundings to the system and the temperature of the water decreases.
Explanation:
The laws of thermodynamics lets us know that energy is neither created nor destroyed but can be converted from one form to another. Also, energy transfer does accompany chemical reactions in the form of heat.
For an endothermic reaction, heat is absorbed by the system from the surroundings. This leads to a drop in the temperature of the surroundings as energy is removed.
This implies that the water temperature decreases.
Reactivity is an impetus For which a chemical substance undergoes A chemical either by itself or with another materialWith an overall release of energy
