There are three ways thermal energy can be transferred: conduction, convection, and radiation.
Convection, a natural method of energy (heat) transfer.
Electrons bumping into each other transferring energy called electricity.
It is called passive diffusion.
thermal insulator
The movement of molecules from an area of high concentration of that molecule to an area of lower concentration is called simple diffusion.
they oth make big or large movement
Thermal energy

Thermal energy
We call material that acts in that way a thermal insulator. Sometimes we shorten it to just insulation, but we need to be clear that we're talking about thermal energy and not, say, electrical energy.
The flow of thermal energy is called heat transfer. It is through the various means of heat transfer that thermal energy moves from one place to another. Heat moves from where it is hot to where it is not. Always. Think it through and it will make perfect sense.
What we normally call heat or thermal energy.
Since the late 60s/early 70s, heat has been considered as energy in transit from a body at a higher temperature to one at a lower temperature. Heat is directly comparable to work, where work describes energy in transit from one form into another.So, heat and work both describe transfers of energy, not energy itself.We can use water as an analogy. When it's vapour, we call it a 'cloud', when it condenses, we call it 'rain', when it's on the ground, we call it a 'puddle'. Well, heat and work are equivalent to 'rain' -water in transit between being a cloud and being a puddle!
Probably "a cat on a hot tin roof"
the process is call OSMOSIS.
Well, it is commonly called just that - "kinetic energy". Of course, you might call it the "energy of movement", because that's what it is all about.
By the way heat is defined in thermodynamics, it is energy moving from one place to another. By analogy, rain is only rain when it is falling. When it is in the clouds we call it a cloud. Once it makes it to the ground it is just a puddle. Generally heat flows because of thermal gradients.
It is called passive diffusion.
