PHYS 2 Chapter Notes - Chapter 17.1 - 17.5: Kelvin, Thermal Expansion, Triple Point
Document Summary
Thermodynamics = the study of energy transformations involving heat, mechanical work, and other aspects of energy and how these transformations relate to the properties of matter. Insulator = a material (ie. wood, plastic foam, fiberglass) that influence two systems more slowly. Delay cold material from being heated up by warmer material and vice versa. Ideal insulator = idealized material that permits no interaction at all between the two systems. Thermal conductor = a material that permits thermal interactions through it. Zeroth 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. Two systems are in thermal equilibrium if and only if they have the same temperature. Pressure of a gas at constant volume increases with temperature. Triple point = unique combination of temperature and pressure at which solid water, liquid water, and water vapor can all coexist.
