Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
