PHYS 2B Chapter Notes - Chapter 17: Kelvin, Thermometer, Thermodynamics
Document Summary
Temperature: related to the kinetic energies of the molecules of a material. Thermal equilibrium: the interaction between the thermometer and the substance causes no further change in the system. Insulator: a material that permits little to no interaction at all between the two systems. 0th law of thermodynamics: if c is initially in thermal equilibrium with both a and b, then a and. B are also in thermal equilibrium with each other. This result is called the zeroth law of thermodynamics. Two systems are in thermal equilibrium if and only if they have the same temperature. Coefficient of linear expansion: the thermal expansion properties of a particular material. Thermal stresses: preventing expansion or contraction and changing the temperature. Heat: the energy transfer that takes place solely because of a temperature difference. Calorie: the amount of heat required to raise the temperature of 1 gram of water from 14. 5 c to 15. 5 c.
