A metal rod at 38°C is placed in a room at a constant temperature of 0°C.

(a) If after 20 minutes the temperature of the rod is 20°C, find the temperature function T(t) that
models the temperature T of the rod at time t. Assume Newton's Law of Cooling.
Note: You must state the differential equation that models this situation and include
how to solve this DE as part of your solution.

(b)Determine the time it will take for the bar to reach 10°C.

(c)Determine the temperature of the metal rod after 15 minutes.

As the temperature of a metal rod varies, so does the resistance and the dimensions of the rod. If a copper rod has a resistance of 4.78 Ω at 20.0°C, determine the resistance of the rod (in Ω) at 120°C by accounting for the changes in both the resistivity and the dimensions of the rod. The coefficient of linear expansion for copper is 1.67 ✕ 10−5 (°C)−1 and the temperature coefficient of resistivity is 4.04 ✕ 10−3 (°C)−1.
