Connecting the statistical and macroscopic approaches to irreversible processes
(a) You add 0.1 kg of water at 0 °C to 0.3 kg of iced tea at 70 °C . Determine the final temperature of the mixture after it reaches equilibrium. The specific heat of iced tea is the same as water. (b) Estimate the entropy change of this system during this process. Is it allowed by the second law of thermodynamics? Explain.
