Thermodynamics refers to a set of laws that provide the ultimate foundation in how the world really works. It helps us understand randomness and disorder in systems and explains the conversion of energy from one form to another, the direction in which heat will flow, and the availability of energy to do work. One of the most useful aspects of

Heat is the movement of molecules within a material. The greater the rate of movement, the greater the heat.

Radiation is the movement of electromagnetic waves through space, such as light waves from the sun. The waves provide energy to the molecules that they contact, causing them to become more active and converting electromagnetic energy into heat energy. All matter emits thermal radiation; most can’t be felt.

The fourth law of thermodynamics is known as the zeroth law. This is because it was formulated after the first three laws but is fundamental to and assumed by the others. It states that if two objects are in thermal equilibrium with a third object, then those two objects are also in thermal equilibrium with each other.
