added to the engine minus the waste heat

Explanation:

The amount of work done by a heat engine equals the amount of thermal energy added to the engine minus the waste heat.

Thermodynamics is used to measure the energy changes that accompanies physical and chemical process.

In a system;

Internal energy = Quantity of heat added - Work done on it

internal energy is designated as ΔU

quantity of heat as Q

work done as W

ΔU = Q - W

so W = Q - ΔU

some of the heat added added to the system goes as waste heat as no system is 100% efficient.

the work done on a system goes in as thermal energy, internal energy and waste heat
