Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What term is given to a reaction which transfers heat energy to the surroundings?
A
Endothermic
B
Reversible
C
Exothermic
D
Activation Energy
Explanation: 

Detailed explanation-1: -The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become hotter. A thermometer is used to detect the temperature increase. Some examples of exothermic reactions are: combustion (burning)

Detailed explanation-2: -Exothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Endothermic reactions take in energy and the temperature of the surroundings decreases. Combined Science. Energy changes.

Detailed explanation-3: -Endothermic reactions take in energy from the surroundings. Reversible reactions are where the products can react to remake the original reactants. If the forward reaction is exothermic, the reverse reaction is endothermic.

Detailed explanation-4: -An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.

Detailed explanation-5: -In an exothermic reaction energy is given out, usually in the form of heat. This can often be detected by a rise in temperature.
