PHYS 123 Chapter Notes - Chapter 20: Quasistatic Process, Rotational Energy, Heat Capacity
Document Summary
A thermal interaction occurs when there is transfer of thermal energy. This energy is denoted by the letter q. The law of conversation of energy holds true for q. q is referred to as the energy transferred thermally. When there is energy transferred into the system ,q is positive and vice versa. A process that doesn"t involve any thermal transfer of energy is called an adiabatic process, q=0. When the volume of the gas decreases the work done on the gas is positive and vice versa. When there is a change from one macrostate to another is called a process. A process is carried out such that the system always remains close to the equilibrium state is called quasistatic. Transferring energy thermally to a system increases its entropy and vice versa. The entropy of a system undergoing a quasistatic adiabatic process does not change. Ideal gas thermometer measures the pressure in a gas sample kept enclosed in a fixed volume.
