As shown below, one side of a rigid, insulated container initially holds 2 m3 of air at 27oC, 0.3 MPa. The air is separated by a thin membrane from an evacuated volume of 3 m3 . Owing to the pressure of the air, the membrane stretches and eventually bursts, allowing the air to occupy the full volume. Assuming the ideal gas model for the air, determine: a) The mass of the air, in kg. b) The final temperature of the air, in K. c) The final pressure of air, in MPa.

Principal Quantities and EOS

A physical quantity represents the physical state of a system. It is expressed as the product of a number and unit. The basic quantities used in science are length, mass, and time. The principal quantities are the quantities that are independent of other quantities.
