Question 3 (14 points]: For this problem we will consider melting of ice at 0C and heating/cooling liquid water. AH (H20) = 6007 J mol-1; Cs(H2O) = 4.184 ) g1001 a) (8 points) How much ice (in g) would you need to add to 250. g of H2O(l) at 25C to make a glass of water at exactly 10C. You may assume that no heat is transferred to the surroundings in this process. m = b) (6 points) What is the entropy change (in JK-1) when 100. g of ice at 0C is melted and heated to 10C? AS
