heat engine?
Vocabulary A-Z
Let us learn some vocabulary
Refrigerator
is a device that uses electric energy to transfer
thermal energy from a cooler location to a warmer
location.
SUMMARY
What are the Uses of Thermal Energy?
A bimetallic coil inside a thermostat controls a
switch that turns a heating or cooling device on
or off. Let’s Begin
Refrigerators
A device that uses electric energy to transfer thermal
energy from a cooler location to a warmer location is
called a refrigerator.
In a refrigerator, a coolant is pumped through pipes
on the inside and the outside of the refrigerator
In a car engine, chemical energy in fuel is
transformed into thermal energy. Some of this
thermal energy is then transformed into
mechanical energy.
