We have two equal size boxes, a and b. each box contains gas that behaves as an ideal gas. we insert a thermometer into each box and find that the gas in box s is at a temperature of 50°c while that in b is at 10°c. this is all we know about the gas in the boxes. which of the following statements must be true? which could be true? explain the reasoning behind your answers.
a) the pressure in a is higher than in b
b) there are more molecules in a than in b
c) a and b cannot contain the same type of gas
d) the molecules in a have more average kinetic energy per molecule than those in b
e) the molecules in a are moving faster than those in b

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
