Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

An automobile engine uses gasoline and in the process of burning the gasoline, a lot of “waste” heat is generated by the engine, this can be explained by

A	kinetic energy
B	potential energy
C	first law of thermodynamics
D	second law of thermodynamics

Explanation:

Detailed explanation-1: -Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself.

Detailed explanation-2: -The second law of thermodynamics indicates that a Carnot engine operating between two given temperatures has the greatest possible efficiency of any heat engine operating between these two temperatures. Irreversible processes involve dissipative factors, which reduces the efficiency of the engine.
