Heat Engine, Pump, Thermal Efficiency

A device that removes heat from a cold body and transfers it to a hot body

• Heat Engine

• Heat Pump

• Steam Engine

• Carnot

Describes the limitations of heat transfer. It states that it is impossible for heat to spontaneously flow from a cold body to a hot body.

• 1st Law of Thermodynamics

• 2nd Law of Thermodynamics

• Newton's Laws of Motion

• Ohm's Law

A system that converts heat to mechanical energy, which can then be used to do mechanical work.

• Heat Pump

• Steam Engine

• Heat Engine

• Heat Engine

Thermal efficiency is represented by the symbol "η"

• True

• False

In which part is the heat engine found in the image?

• A

• B

• C

• D

What device is being shown in the picture?

• Heat Engine

• Refrigerator

• Hot Reservoir

• Heat Pump

It expresses the fraction of heat that becomes useful work, a dimensionless performance measure of a device that uses thermal energy

• Thermodynamics

• Carnot Cycle

• Thermal Efficiency

• Heat Cycle

The expansion of gas during cooling and gas compression when cooled makes the Stirling engine work.

• True

• False

Answer explanation

It should be "heating" not "cooling"

With regards to the image, which part is the hot reservoir?

• A

• B

• C

• D

A. Heat Engine is a device that transforms thermal energy into mechanical energy.

B. Heat Pump is device that removes heat from a cold body and transfers it to a hot body

• A is correct

• B is correct

• Both are correct

• Neither of these options are correct
