5. Apply Concepts A heat engine has an energy input of 300 J. Its output of use-
ful energy is 150 J. What is the total output of non-useful energy from the heat
engine? Explain how you know.

Sagot :

Given the data from the question, the total output of non-useful energy from the heat engine is 150 J

What is a heat engine?

A heat engine is a device / equipment that can convert or transfer thermal energy into useful-work. Some examples of heat engines include

  • refrigerators
  • Internal combustion
  • Thermal power station
  • firearms  
  • heat pumps

How to determine output non-useful energy

From the question given above, the following data were obtained:

  • Input energy = 300 J
  • Output (useful) = 150 J
  • Output (non-useful) =?

Output (non-useful) = Input – Output (useful)

Output (non-useful) = 300 – 150

Output (non-useful) = 150 J
