WebIn conduction, heat is transferred from a hot temperature location to a cold temperature location. The transfer of heat will continue as long as there is a difference in temperature between the two locations. Once the two locations have reached the same temperature, thermal equilibrium is established and the heat transfer stops. WebIncreases in temperature causes a linear decrease in metals’ conductivity because of phonon-electron interactions. Since temperature is a measure of how quickly the atoms vibrate (we can call this vibration a “phonon”), increased vibration can interact with electrons passing through.
