Thermal energy
Definition.
Thermal energy is the energy an object has because its particles are moving, and it is felt as heat.
How does thermal energy cool things down?
A hot object has lots of thermal energy.
The air or nearby objects are cooler.
Thermal energy moves from hot to cold.
The hot object loses energy.
Losing energy = it cools down.
Ways thermal energy leaves an object:
Conduction – heat moves by touching.
Convection – heat moves through air or water.
Radiation – heat spreads as waves.
Key Points.
Thermal energy is heat energy.
It comes from moving particles.
Hotter objects have more thermal energy.
Thermal energy moves from hot to cold.
Energy often ends up as thermal energy.
What is energy?
Energy is the ability to do work or cause change.
Examples:
Moving.
Heating.
Lighting a bulb.
Key points.
Energy makes things move.
Energy makes things change.
Energy is never created or destroyed.
It only changes form.
Fun fact:
Even when something feels cold, it still has thermal energy it just has less than your hand, so heat flows from you to it, making your hand feel cold.
