Temperature and Heat
Written by tutor Nathan B.
Temperature and heat in physics can be understood through several approaches and each is advantageous for different purposes. Generally, these approaches fall into two categories depending on the size of the basic objects under consideration: Statistical Mechanics and Thermodynamics. Statistical Mechanics starts from atoms and builds up to...
Heat and Energy

The world is composed of many particle systems interacting in space and time via four forces – gravity, electromagnetism, the strong force, and the weak force. In modern physics, the mechanism by which these forces function is described mathematically as a “field.” The field theory of gravity is General Relativity, in which a mass distribution...
