In some countries, liquid nitrogen is used on dairy trucks instead of mechanical refrigerators. A 3.00-hour delivery trip requires 150 L of liquid nitrogen, which has a density of 808 kg/m3.
(a)
Calculate the heat needed in kilocalories to evaporate this amount of liquid nitrogen and raise its temperature to 3.50°C. (You must use cp, and you can assume it is constant over the temperature range.) This is the amount of cooling the liquid nitrogen supplies.
