QUESTION:

Consider an ideal gas at  and . As a result of some disturbance, the conditions of the gas change to  and . Estimate the change in the specific volume of the gas using (a) Eq. 12-3 and (b) the ideal-gas relation at each state.

ANSWER:

Step 1 of 4

The state of an ideal gas is altered slightly. The change in the specific volume of the gas is to be determined using differential relations and the ideal-gas relation at each state.

It is assumed that the gas is air and air is an ideal gas.

 The gas constant of air is  (Table A-1).
