1.A frictionless piston-cylinder contains 2kg of nitrogen at 100 kPa absolute and 300 deg K. The system is compressed polyprotically at a 1.4 exponent (n) until the nitrogen reaches a final temperature of 360 deg K.
Plot this process on a P-V diagram and a P-T diagram.
2.The solids in a specimen have a specific gravity of 2.65. If the oven-dry mass of the specimen is 25kg, what is the volume of the solids in it?
