Unreasonable Results - A slightly deranged Arctic inventor surrounded by ice thinks it would be much less mechanically complex to cool a car engine by melting ice on it than by having a water-cooled system with a radiator, water pump, antifreeze, and so on. (a) If 80% of the energy in 1.00 gal of gasoline is converted into “waste heat” in a car engine, how many kilograms of 0C ice could it melt? (b) Is this a reasonable amount of ice to carry around to cool the engine for 1.00 gal of gasoline consumption? (c) What premises or assumptions are unreasonable?

Suppose four 30-g ice cubes are added to a glass containing 200 cm3 of orange juice at 20,0°C.You may assume that the orange juice has a density and specific heat capacity the same as water namely: Density = 1,0 g∙cm–3 and specific heat = 4,184 J/gK The heat of fusion (of water) is 333 J/g.Your task is twofold. You must determine:a) Whether or not all the ice will melt; andb) If your finding is that some ice will be left in the juice, you must calculate what mass of ice will be present the moment when thermal equilibrium is reached.
