Video Summary

Energy is the ability to do work. Thermodynamics is the branch of physics that deals with heat and its relation to other forms of energy. The first law of thermodynamics states that energy cannot be created or destroyed, but it can be transferred from one form to another. The second law of thermodynamics states that the entropy of an isolated system always increases. Entropy is a measure of disorder or randomness. Energy and thermodynamics are important concepts in many fields, such as physics, chemistry, biology, and engineering.
