Question

In a heat engine heat energy is converted into mechanical energy.

• A. True
• B. False

Answer 1

The correct option is A True

Heat engine

1. When a system undergoes mechanical work, its internal energy grows.
2. A device known as a Heat engine is used to execute the reverse process, which is when mechanical work is achieved at the expense of internal energy.
3. Heat engines accomplish this duty of converting energy from one form to another by utilizing the temperature differential between two bodies. The body that is at a higher temperature is referred to as a "source," whereas the body that is at a lower temperature is referred to as a "sink."
4. The basic function of a heat engine is to extract heat energy from bodies at higher temperatures, turn a portion of it into the mechanical effort, and then transport the remaining energy in the form of heat to bodies at lower temperatures.
5. Demonstrating with the help of diagram

Hence, it is true that in a heat engine heat energy is converted into mechanical energy.
