A copper wire is connected to an ideal battery at room temperature. The current increases by a factor of 78 when the wire is immersed in liquid nitrogen (temperature 77 K). Ignoring changes in the wire's dimensions, and assuming that the number of conduction electrons per unit volume (n) does not change, find the change in each of the following quantities: the resistance, the resistivity, the electric field in the wire, the drift speed, and the power dissipated.
