Thermodynamics is a branch of physics that is concerned with heat energy and temperature and their interaction with matter.
More correctly, thermodynamics involves examining the principles behind the movement of heat.
Some concepts may already be known to you such as the idea of heat transfer via conduction convection and radiation. You may already know about the changes of state, and that certain substances will melt or boil a different temperatures. But what are the physics principles as to why changes of state occurs?
In these series of lessons, will explore some Thermodynamic concepts, (though not exhaustive.)
We will start by looking at what temperature is, and then examine to important properties of materials called the specific heat capacity and latent heat.
We will also examine how heat is transferred from substance to substance via conduction convection and radiation, and look at the rate of heat transfer.

Heat vs Temperature
Colloquially when it is a hot day we refer to the temperature. So people often equate heat with temperature. But they are not the same. When you take a pizza out of the oven, the crust does not seem to be as hot as the melted cheese on top however they are both the same temperature.
This video examines the difference between temperature and heat. It also examines the zeroth law of thermodynamics and why substances feel cold.
