What it thermal energy?

Answer 1

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!

Answer 2

Heat energy is also called thermal energy. It is the energy inside substances, or the movement of the atoms and molecules that make up the substances. The warmer a substance/object is, the faster the molecules are vibrating or moving. If a substance is cold, that means the molecules aren't moving or vibrating very much. One way to measure thermal/heat energy is the temperature. The temp. of a substance shows how much thermal energy it has in it.

Answer 3

Heat is a form of energy that can be transferred from a region of higher temperature to a region of lower temperature. Heat can be transferred by conduction,convection or radiation.

Answer 4

Thermal energy is a FORM of energy. It is the energy of heat.

Answer 5

Heat energy is the vibration of molecules in a substance, or the average kinetic energy of the molecules in the sample

Answer 6

Thermal energy
