Question

We have a canister of water with a temperature of 25°C. Through an isothermal reversible process, we extract heat 666 kJ from the water. a) What is the entropy change of the system that only includes the water canister? b) What is the entropy change of the entire place, i.e. the system that includes BOTH the water canister and its surroundings?

Step 1

Given that the heat extracted from the water is 666 kJ and the temperature is 25°C (which is 298 K), we can use the formula for entropy change: ΔS = -Q/T ΔS = -(666 kJ)/(298 K) ΔS = -2.23 kJ/K Show more…
