PHYS 117 Chapter Notes - Chapter 11: Black Body, Emissivity, Thermal Conductivity
Document Summary
Physics 117 chapter 11 energy in thermal processes. Internal energy is the energy associated with the atoms and molecules of the system. The internal energy includes kinetic and potential energy associated with the random translational, rotational, and vibrational motion of the particles that make up the system, and any potential energy bonding the particles together. Heat is the transfer of energy between a system and its environment due to a temperature difference between them. Specific heat of water: 4. 186 j/kg: c . Calorimetry problems involve solving for an unknown quantity, usually either a specific heat or temperature. Thermal conduction (or conduction): the energy transfer process associated with a temperature difference. Thermal conductivity, k, is a proportionality constant that depends on the material. Substances that are good conductors have large thermal conductivities, and good insulators have low thermal conductivities. Convection: the transfer of energy by the movement of the substance.
