fast i think
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.
Heat transfer
Kinetic energy is the type of energy that depends on how fast the molecules in a substance are moving.
Temperature
The speed at which molecules of alcohol move can vary depending on factors such as temperature. However, on average, the molecules of alcohol move at speeds of around several hundred meters per second.
heat transfer.
Very fast.
How fast molecules are moving. If they are moving fast its hot, but if they are moving slow it is cold
They vibrate while they move fast.
The temperature increase.
