In some countries liquid nitrogen is used on dairy trucks instead of mechanical refrigerators. a 3 hour delivery trip requires .200 m^3 of liquid nitrogen which has a density of 808 kg/m^3, assuming it is already at its boiling temperature of -195.8c, calculate the heat transfer necessary to evaporate this amount of liquid nitrogen and raise its temperature to 4.0c (nitrogen: lv=201 kj/ kg, cgas = 1040 j/kgc

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
