Aglass flask whose volume is 1000 cm3 at a temperature of 0.200 ∘c is completely filled with mercury at the same temperature. when the flask and mercury are warmed together to a temperature of 52.0 ∘c , a volume of 8.50 cm3 of mercury overflows the flask.
if the coefficient of volume expansion of mercury is βhg = 1.80×10−4 /k , compute βglass, the coefficient of volume expansion of the glass.
express your answer in inverse kelvins.

Which would not reduce the amount of green house gasses in the air

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

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.
