This exercise is from high school. A conductive wire has a resistance of 36 ohms at 32 ° C centigrade and 63 ohm at 23 ° C. Calculate the temperature coefficient and the resistance it presents if the temperature increases by 100 ° C compared to the initial one. how can you help?

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
