Thermal energy
Definition
Thermal energy is the energy produced by heat due to the movement of tiny particles inside an object.
Main details
Everything around us is made of tiny particles.
These particles are always moving.
When particles move faster, the object has more thermal energy.
When particles move slower, the object has less thermal energy.
Hot objects have more thermal energy than cold objects.
Thermal energy always flows from a hot object to a cold object.
Thermal energy is related to temperature, but they are not the same.
Examples
A hot cup of tea has more thermal energy than cold water.
Fire gives thermal energy to keep us warm.
The Sun provides thermal energy to the Earth.
An iron box uses thermal energy to remove wrinkles.
Rubbing hands makes them warm because thermal energy is produced.
Interesting Points
All objects have thermal energy, even cold ones.
Thermal energy helps in cooking food.
It is used in heaters, stoves, and engines.
When objects touch, thermal energy can transfer between them.
Fun fact
Your body produces thermal energy all the time to keep you warm.
