Gas. Lets take water for an example. For it to be liquid it can be room temperature however for it to be a gas, it needs to break all of its inter molecular forces and hydrogen bonding. This requires alot of thermal energy or heat as it has to become 100 degrees for water to boil and become a gas.
Combustion (fire or burning) is arguably the most common example of converting chemical energy into thermal energy. But consider that all animals create a bit of thermal energy converting chemical energy into heat (as well as some mechanical energy) when they move.
kinetic energy
The amount of excitement in a solid, liquid ar gas. For example a gas has the most amount of energy and solids have the least amount.
Thermal energy I suppose, but in most cases it is used for electricity. The steel industry uses coal (or coke rather) in blast furnaces.
There can be many, kinetic (explosion), radiation (light) but the most common and the one people think of is thermal.
Most things have thermal energy. Thermal energy is comes from heat and therefore anything that can generate heat has thermal energy. All living things have thermal energy.
On Earth, the greatest source of thermal energy would be at the earth's core.
Thermal energy is the most difficult to convert into other forms of energy.
Thermal energy is the most difficult to convert into other forms of energy.
Thermal energy is just mechanical energy on a molecular level (e.g. the motion of individual molecules). Therefore, thermal energy is stored in every molecule of the subject.
Most of it will be converted to heat, via friction.
Particles of matter have their least kinetic energy in the solid phase and their greatest kinetic energy in the gas phase.
gas
Most of the potential energy will be converted to thermal energy in this case.
This is the solid phase.
The most common and easiest way to measure thermal energy is with the use of a thermometer. The thermometer measures heat. Heat is the output of thermal energy.
