Molecules in motion
The amount of energy an object has because of its moving molecules is called kinetic energy. This energy is determined by the mass of the object and the speed at which its molecules are moving.
Heat is transferred by conduction when fast-moving molecules collide with slower-moving molecules, transferring kinetic energy. This causes the slower molecules to speed up and the faster molecules to slow down, leading to a transfer of thermal energy from hot regions to cold regions within a material.
It's Melting, the molecules are moving therefore we have a liquid.
the air molecules
When fast moving molecules touch other molecules, it is called a collision. These collisions can lead to the transfer of energy and changes in the motion or state of the molecules involved.
Molecules moving with kinetic energy can collide with other molecules or surfaces, transfer energy to other molecules through collisions, and change direction due to interactions with other molecules in their environment.
If molecules are bunched up is this hot or cold
it is a measure of moving molecules, or molecules in motion
Heat transfer
Kinetic energy is the type of energy that depends on how fast the molecules in a substance are moving.
