Quizplus · Accepted Answer

A reversible process is one that can be undone without any change in the overall system or surroundings, and no energy or heat is wasted. The process of slowly pouring hot water into cold water while allowing the beakers to achieve ambient temperature levels can be reversed by simply pouring the water back into their original containers, without any change in the system or surroundings. On the other hand, firing a bullet from a gun or striking a match are irreversible processes as they can't be undone. Quick pouring hot water into colder water is an irreversible process because it causes the temperature to rapidly equalize and doesn't allow for a gradual and reversible temperature change.
