Explain why you should not buy an engine made of bronze if the salesman tells you it is 90% efficient.

Solution

REASON 1:

Thermal conductivity of bronze is more..that\'s why all the heat generated inside the engine is conducted through the wall...thermal efficiency is decreased...that\'s why it is not used....

REASON 2:

heat generation is more in the engine at some temperature heat transfer is stopped that\'s why bronze is not used
