Thermal PhysicsA thermodynamic system is an isolated portion of space, separated from surroundings and a transfer of only energy and matter.Macroscopic(thermal property that determines whether or not a system is in thermal equilibrium with other systems) quantitiesoPressureoVolumeoTemperatureoMassMicroscopic(a measure for the total kinetic energy of the molecules in the system).Temperature: thermometer – a device having some measurable physical quantities that changes with temperature. Thermal Equilibrium:Heat is energy in transit.The heat that an object absorbs (or loses) is proportional to the temperature change of the object. Q = C∆T = C(Tf– Ti).Molar specific heat:When an object absorbs energy as heat, the temperature does not necessarily rise. The object may change its physical stateThe change of physical state is also called
