Below are letters corresponding to the sketches of the moon at the top of page two of your lab handout. Put the letters in order, starting with Waning Gibbous. We have labeled the phases to help you. There are two that while they are the same phase (in name), they are not quite the same shape, so they can be placed in order with different rankings. a. trueb. false

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
