Thermal energy
Definition:
Thermal energy is Heat . It is the energy that makes things warm or hot.The tiniest particles in everything move — when they move faster, the thing gets hotter.When they move slowly, it gets cold.
Main Points:
Thermal energy comes from moving particles inside everything.
More movement = more heat.
Less movement = less heat.
Heat always moves from hot → cold.
You can feel thermal energy when you touch something warm.
Interesting Points:
When you rub your hands, they get warm because you create thermal energy.
The Sun gives us huge amounts of thermal energy — that’s why we feel warm in daytime.
Even ice has thermal energy! Its particles still move, but very slowly.
Fun Fact:
Thermal energy can make popcorn POP!The heat makes the water inside corn kernels expand until— BOOM! Popcorn time!
