8–75 Oxygen gas is compressed in a piston–cylinder device from an initial state of 0.8 m3/kg and 258C to a final state of 0.1 m3/kg and 2878C. Determine the entropy change of the oxygen during this process. Assume constant specific heats.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?

The air in an automobile tire with a volume of 0.015 m3 is at 32°c and 140 kpa gage. determine the amount of air that must be added to raise the pressure to the recommended value of 206 kpa gage. assume the atmospheric pressure to be 128 kpa and the temperature and the volume to remain constant.[r-0.287 kj/kgk]
