A vessel which contains an ice-water mixture at 0c is in, Ask an Expert

Academics

A vessel which contains an ice-water mixture at 0C is in thermal contact with a water-steam mixture at 100 C.

A. During a 10 minute period, 35 grams of steam condenses into water. How much energy flowed out of the water-steam mixture? (Signs Matter!) kJ

B. Assuming that all of the energy flowing out of the water-steam mixture goes into the water-ice mixture, how many grams of ice melts?

C. What is the change in the entropy of the water-steam mixture at 100C? (Signs Matter!)

D. What is the change in the entropy of the water-ice mixture at 0C? (Signs Matter!) (Verify to yourself that the 2nd law of thermodynamics is satisfied)
