Question

True of false

The amount of energy entering a closed system is usually slightly greater than the amount of energy exiting the system.

Answer 1

True because as based on the first law of thermodynamics we can say that for example in cyclic process the system does the net work on its surrounding, we can physically observe that the heat entering the system but some heat leaves the system to. The law also states that the total amount of energy remains constant but varies accorfing to the system (large amount of fuel is required to lift of rocket from surface) energy cannot be destroyed it can onky be transferred.
