Thermodynamics is a branch of physics which deals with the relationship on how heat and other forms of energy. It shows how heat is converted into different forms of energy and how it reacts. The video below shows how heat is touching a pop can wrapped in tin foil, on the end of the pop can he squeezes some gas onto the end, which makes it go flying across the room. Then the soup can that is left over is wrapped with a flame on the inside which is caused by the left over gas.

The four laws of Thermodynamics:

The zeroth law states that when two bodies are at the same temperature with some third body, then they're at the same temperature with each other.

The first law states that the total increase in the energy of a system is equal to the increase in thermal energy plus the work done on the system.

The second law states that heat energy cannot be transferred from a body at a lower temperature to a body at a higher temperature without the addition of energy.

The third law states that that the entropy of a pure crystal at absolute zero is zero. As explained above, entropy is sometimes called "waste energy," i.e., energy that is unable to do work, and since there is no heat energy whatsoever at absolute zero, there can be no waste energy. Entropy is also a measure of the disorder in a system, and while a perfect crystal is by definition perfectly ordered, any positive value of temperature means there is motion within the crystal, which causes disorder. { }
