Question

A heat engine is a device able to transform work into heat. a. True b. False

Answer 1

Answer:

Option B: False

Explanation:

A heat engine is a device which operates in a manner that heat is converted into mechanical work.

A simple example of a heat engine is a drinking bird. The oscillatory motion of the drinking bird is as a result of the thermal expansion and contraction of a chemical compound in its beak, which creates an imbalance in its position of equilibrium. This causes it to oscillate.

Heat engines usually work by extracting heat once there is a temperature gradient available in the system and using it to perform work. Another good example is the internal combustion engine. It extracts heat from the explosion of the burning fuels and uses it to power the car.
