Select one:
a. heat engine
b. steam engine
c. steam turbine
d. water turbine

Answer 1

A machine that converts heat energy to mechanical energy is called a heat engine, which functions on thermodynamic principles through different processes to perform work.

Step-by-step explanation:

The type of machine that converts heat energy to mechanical energy through a series of repetitive thermodynamic operations is known as a heat engine. Heat engines operate on the fundamental laws of thermodynamics, using heat transfer to perform work. This includes various engines such as gasoline and diesel engines, jet engines, and steam turbines.

A heat engine typically operates through cycles consisting of different thermodynamic processes such as isobaric, isochoric, isothermal, and adiabatic processes. These processes occur in a way that heat transfer leads to work being done, as shown schematically in various figures explaining the application of the first law of thermodynamics to heat engines.
