Topic hierarchy

12.1: Introduction
The kinetic theory of gases describes a gas as a large number of small particles (atoms and molecules) in constant, random motion.
12.2: Temperature and Temperature Scales
Celsius, or centigrade, is a scale and unit of measurement for temperature. It is one of the most commonly used temperature units.
12.3: Thermal Expansion
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
12.4: Ideal Gas Law
The ideal gas law is the equation of state of a hypothetical ideal gas (in which there is no molecule to molecule interaction).
12.5: Kinetic Theory
Pressure is explained by kinetic theory as arising from the force exerted by molecules or atoms impacting on the walls of a container.
12.6: Phase Changes
During a phase transition, certain properties of the medium change, often discontinuously, as a result of some external condition.
12.7: The Zeroth Law of Thermodynamics
The Zeroth Law of Thermodynamics states that systems in thermal equilibrium are at the same temperature.
12.8: Thermal Stresses
Thermal stress is created when a change in size or volume is constrained due to a change in temperature.
12.9: Diffusion
Diffusion is the movement of particles from regions of high concentration towards regions of lower concentration.
