Cooling and freezing.
This question requires a context. Thermal energy exists everywhere. But in general, too much thermal energy leads to overheating.
The answer is heat engine.
Thermal energy
There are different types of thermal energy like conduction, convection, and radiation. But the one that requires objects to touch is conduction.
Freezing is the process where a substance changes from a liquid to a solid by extracting heat energy. So, freezing actually involves the removal of thermal energy from a substance rather than adding thermal energy.
No. It takes energy to boil a substance.
Yes. When ice is converted to water, thermal energy is required. When the water is converted back to ice, the same amount of thermal energy is released.
The moving of hands requires mechanical energy.
Convection requires a liquid or gas.
Radiation
Freezing is the process by which a substance changes from a liquid state to a solid state by removing thermal energy. This removal of thermal energy causes the particles in the substance to slow down and come closer together, forming a solid structure.
