A 100 Ohm resistor dissipates heat to its surroundings, isothermally. The resistor maintains a constant temperature of 300 K. A current of 10 A is passed through the resistor for 300 seconds.
A) What is the change in entropy of the resistor?
B) How much energy does the surroundings absorb?
C) What is the change in entropy of the surroundings?
D) What is the change in mass of the surroundings?
