1. you are given a .5 m^3 container containing 9 moles of an ideal diatomic gas at 0° C, and you want to allow it to reach room temperature (20° C) while staying at the same pressure. You have a choice of holding the volume constant while heating it (process A) and then slowly decompressing the gas isothermally (process B) or simply heating it while maintaining pressure (process C).
a) what is the change in entropy of the gas in going from the initial state to the final state?

A monatomic ideal gas initially fills a container of volume V = 0.15 m3 at an initial pressure of P = 360 kPa and temperature T = 275 K. The gas undergoes an isobaric expansion to V2 = 0.55 m3 and then an isovolumetric heating to P2 = 680 kPa. a) Calculate the number of moles, n, contained in this ideal gas. b) Calculate the temperature of the gas, in kelvins, after it undergoes the isobaric expansion. c) Calculate the...

1. An ideal gas assumes molecules are point particles and do not interact with each other. In reality, molecules occupy space! To correct for this, the ideal gas equation of state is adjusted to take the volume occupied by the molecules into account for a real gas: PV = nRT or P = nRTV is modified to P = nRT/(V-nb) (IDEAL GAS) (REAL GAS Where "b" is related to the...
