Asample of nitrogen at a pressure of 0.127 atm and a temperature of 81.5 k is compressed at constant temperature to a pressure of 42.6 atm. which of the following are true? choose all that apply the solid initially present will vaporize. the final state of the substance is a liquid. the sample is initially a solid. one or more phase changes will occur. the sample is initially a gas.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
