Thermodynamics is the study of the conversion of one form of energy to another. To understand the fundamental concept of thermodynamics, it is important to examine and define some properties such as temperature, volume, pressure and density.
Energy is the ability to do work.
Types of energy
Properties of energy
- Energy is never lost nor created
- It is transferred from one form to another
- All types of energy are released as heat
Temperature: temperature of a substance is a measure of the random motion of the molecules of the substance. It is the property that describes the hotness of the substance.
