    Thermal Physics Thermal physics is the study of Temperature Heat How these affect matter Concerned with the concepts of energy transfers between a system and its environment and the resulting temperature variations Concerns itself with the physical and chemical transformations of matter in all of its forms: solid, liquid, and gas

    Heat The process by which energy is exchanged between objects because of temperature differences is called heat Objects are in thermal contact if energy can be exchanged between them Thermal equilibrium exists when two objects in thermal contact with each other cease to exchange energy

    Zeroth Law of Thermodynamics If objects A and B are separately in thermal equilibrium with a third object, C, then A and B are in thermal equilibrium with each other. Allows a definition of temperature

    Thermometers Used to measure the temperature of an object or a system Make use of physical properties that change with temperature Many physical properties can be used volume of a liquid length of a solid pressure of a gas held at constant volume volume of a gas held at constant pressure electric resistance of a conductor color of a very hot object
