Question

A heat engine:
Select one:
1. uses positive work done on the system to transfer heat from a low temperature reservoir
uses positive work done on the system to transfer heat from a low temperature reservoir
uses positive work done on the system to transfer heat from a low temperature reservoir
to a high temperature reservoir
2. converts heat input to an equivalent amount of work
3. converts work to an equivalent amount of heat
4. takes heat in, does work, and loses energy as heat

Answer 1

Answer:

dnt know. sorry for this

Answer 2

Answer:

The correct option is option 4) takes the heat in, does work, and loses energy as heat

Explanation:

Among the four options given the correct option is option 4 about the heat engine.

In this option, we have been mentioned that the heat engine takes the particular heat in, does the work, and then loses the energy as heat to the environment.

This statement is correct.

A heat engine is designated as a system that makes use of thermal energy which is heat in order to do mechanical work.

This generally takes place by converting the taken heat into mechanical energy. This particular energy is then used to do the work.

The key characteristic property of the particular heat engine is that the substance with which the work is usually done goes from a high or higher temperature to a lower temperature.

Hence, it loses the amount of heat it has as it does the work.
