Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A reaction that gives off heat to its surroundings is:
A
exothermic
B
endothermic
C
endergonic
D
none of these
Explanation: 

Detailed explanation-1: -An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”

Detailed explanation-2: -What is an Exothermic Reaction? An exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction.

Detailed explanation-3: -When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases. You can monitor changes in temperature by placing a thermometer in the reaction mixture.

Detailed explanation-4: -The exothermic reaction is the opposite of an endothermic reaction. It releases energy by light or heat to its surrounding. A few examples are neutralisation, burning a substance, reactions of fuels, deposition of dry ice, respiration, solution of sulphuric acid into water and much more.
