the faster the atoms move the more space they need n the more heat they produce . the slower the atoms move they less room they need n the colder an object is.
examples:
think of steam hot it expands n needs to escape the tea pot or what ever n moves fast enough to make that noise.
my teacher used an examples of students. atoms don't wanna bump into each other so lets say if the atoms (kids) were to walk around the room nice n calm we could do that without bumping into each other n we wouldn't get hot n sweaty. but if we were to run around the class room we would start getting hot n bump into each other n need more room n expand.
n yeah that's all i know :)
what do atoms and molecules have to do with heat energy?
the atoms and molecules in matter are always moving.
Heat energy
heat...
That is called heat energy.
The measurement of the energy or heat in matter involves measurement of average speed of atoms and molecules.
Thermal energy is the moment of atoms and molecules in a substance that causes heat.
heat...
Heat energy
Heat.
Heat gives energy to the molecules or the atoms.hence the energized atoms or molecules start vibrating and their power of bonding with other atoms or molicules become weak.
atoms or molecules
Thermal (heat) energy - which is the kinetic energy of atoms/molecules.
That is called heat energy.
The measurement of the energy or heat in matter involves measurement of average speed of atoms and molecules.
Thermal energy is the moment of atoms and molecules in a substance that causes heat.
For one thing, heat is a radiant form of energy. When atoms and molecules have energy, they oscillate at a certain rate. Due to this movement, there is energy expended, and one of the byproducts of this expenditure is thermal radiation, heat being of that category. The more energy in process within atoms and molecules, the more thermal radiation, i.e. more heat.
it is related because heat is temperature and temperature tells how fast molecules move and thermal energy is kinetic + potential energy
the atoms use the energy to move the molecules
