In each cycle of its operation, a heat engine expels 2 400 J of energy and performs 1 800 J of mechanical work. (a) How much thermal energy must be added to the engine in each cycle? (b) Find the thermal efficiency of the engine.

(a)

To determine
how much thermal energy must be added to the heat engine in each cycle.

Explanation

Given Info:

The energy expels by the heat engine is 2400J .

The work done by the heat engine is 1800J

Formula to calculate the thermal energy added to the engine in each cycle is,

|Qh|=Weng+|Qc|

• Weng is the work done by heat engine
• Qc is the energy expelled by the heat engine

Substitute 2400

(b)

To determine
the thermal efficiency of the heat engine.
