If the colder block originally weighed 200g and the warmer, Ask an Expert

Academics

Two blocks of ice, one at -30 degrees C and another -50 degrees C, are brought into thermal contact within a perfect thermos and allowed to reach thermal equilibirum. If the colder block originally weighed 200g and the warmer one 100g, calculate the final temperature and the entropy change of the universe for this process.
