#1: if an electron gains energy, what may happen to it?

a. it may move to a higher energy level.

b. it may drop to a lower energy level.

c. it will never change location

Which changes of state do the labels represent? a: b: c:

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.

How will the system respond to a temperature increase?
