In the 1970s cartoon The Super Friends, the Wonder Twins helped Superman and others fight crime. One of the Wonder Twins was Zan, who was able to take on the form of H2O in its various phases (ice, liquid water, water vapor). After taking a physics class, he decides to conduct a little experiment by turning into an ice igloo in the park on a hot day. (a) If his total mass as an igloo is 64.50 kg and he starts with a temperature of −13.50°C, how much heat must flow into him to completely melt his body? J(b) He continues absorbing energy up to the point where he would start to vaporize (100.0°C). How much more heat is required to raise his temperature to the vaporization point? J(c) How much more heat is required to turn him into water vapor at 100.0°C? J(d) If we model the water vapor molecules making up his body as having only six degrees of freedom, what is the average kinetic energy of one of the water vapor molecules that make up Zan? (Consider the case when Zan is water vapor at…

Professor Modyn uses liquid methane for a cryogenic process. The critical temperature of methane is 191 K; thus, methane must be maintained below 191 K to keep it in the liquid phase. Properties of liquid methane at various temperatures and pressures are given in the table below.
