How much energy (in joules) is required to evaporate 0.0005 kg of liquid ammonia to vapor at the same temperature?

It is 5.5 km from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/h (which uses up energy at the rate of 700 W), or you could walk it leisurely at 3.0 km/h (which uses energy at 290 W).
