[" Even carnot engine cannot give "100%" efficiency "],[" because we cannot "]

Explain why a Carnot engine cannot have 100% efficiency?

Even carnot heat engine cannot give 100% efficiency. Explain why OR can you design a heat engine of 100% efficiency? Explain ypur answer. OR A heat engine with 100% efficiency is only a theoretical possibility. Explain.

Why is a heat engine never 100% efficient ?

Efficiency of Carnot engine is 100% if

Assertion: The efficiency of a carnot engine cannot be 100% . Reason: This is because sink of heat engine cannot be maintained at 0 K .

Efficiency of Carnot engine

An ideal heat engine can be 100% efficient if its sink is at

Why can't a machine be 100% efficient?
