A 2.64-kg copper part, initially at 400 K, is plunged into a tank containing 4 kg of liquid water, initially at 300 K. The copper part and water can be modeled as incompressible with specific heats 0.385 kJ / kg ·K and 4.2 kJ / kg ·K. respectively. For the copper part and water as the system, determine (a) the final equilibrium temperature, in K, and (b) the amount of entropy produced within the tank, in kJ / K. Ignore heat transfer between the system and its surroundings. | Numerade

A 1.5-kg copper block at 200^∘ C is quenched in a water bath containing 6 kg of water at 20^∘ C. Assume that the specific heats of copper and water are respectively 385 J / kg-K and 4179 J / kg-K with no heat loss to the surroundings and determine (a) the final equilibrium temperature, (b) the entropy change of the copper block, and (c) the entropy change of the water. | Numerade

(a) In air at 0^∘ C, a 1.60 -kg copper block at 0^∘ C is set sliding at 2.50 m / s over a sheet of ice at 0^∘ C. Friction brings the block to rest. Find the mass of the ice that melts. (b) As the block slows down, identify its energy input Q, its change in internal energy ΔFint , and the change in mechanical energy for the block-ice system. (c) For the ice as a system, identify its energy input Q and its change in internal energy ΔFint . (d) A 1.60 -kg block of ice at 0^∘ C is set sliding at 2.5
