A20.0 kg block of ice is sitting in a cooler. the temperature of the ice is 0.0ºc when it is put into the cooler. as it melts, how much heat does the block of ice absorb? (remember hf of water is 3.34 x 105 j/kg) a. 8.68 x 104 j c. 2.36 x 104 j b. 6.68 x 106 j d. 3.68 x 106 j

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
