Thermal energy (often wrongly called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
Thermal energy is energy that comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature.
The molecules and atoms that make up matter are moving all the time. When a substance heats up, the rise in temperature makes these particles move faster and bump into each other.
Thermal energy is the energy that comes from the heated up substance. The hotter the substance, the more its particles move, and the higher its thermal energy.
Thermal energy is produced when and atoms or molecules
and then smash into each other or .


A) Conduction
B) Convection
C) Radiation

A) In which process does heat transfer occur between objects by direct contact? .
How is this boiling pot an example of all three types of heat transfer?

The heat from the fire touching the pot is an example of . But when the water at the bottom of the pot heats up, it rises transferring energy to the colder molecules at the top in a cycle and this is an example of . When someone goes near the pot, they can feel the heat coming from the fire and the hot pot in waves, this is an example of .
