A device primarily used for this purpose is an array of alternating p- and n-type semiconductors sandwiched between two conductors, one of which has a current passed through it to use the Peltier effect.
A device primarily used for this purpose is an array of alternating p- and n-type semiconductors sandwiched between two conductors, one of which has a current passed through it to use the Peltier effect. The coefficient of performance for devices that perform this process is the reciprocal of the Q-sub-h over Q-sub-c minus one. Steven Chu's Nobel-winning research was in the use of lasers and the Doppler effect to perform this process. This happens to the gas during the isentropic expansion step of the Carnot cycle. A law named for it states that the time derivative of (*) temperature is equal to a negative proportionality constant times the difference in temperature between a body and its surroundings; said law was derived by Isaac Newton. For 10 points, name this process in which heat is transferred away from a body.
