Question

A pressure versus volume (??pV) diagram for a system is shown in the figure. The arrows of the curve indicate the direction of the process, and the points of interest are labeled. The values for the points in the diagram are shown in the table.

Volume (m^{3}) |
Pressure (Pa) |
---|---|

?0=25.4V0=25.4 | ?0=1.37×104p0=1.37×104 |

?1=19.6V1=19.6 | ?1=1.37×104p1=1.37×104 |

?2=17.0V2=17.0 | ?2=4.50×103p2=4.50×103 |

?3=13.3V3=13.3 | ?3=4.50×103p3=4.50×103 |

?4=13.3V4=13.3 | ?4=3.48×103p4=3.48×103 |

?5=8.70V5=8.70 | ?5=1.57×103p5=1.57×103 |

Calculate the amount of work done on the system from 0–2 (?02W02) and then for the entire curve from 0–5 (?05W05).

Answer #1

Answer question

A pressure versus volume (pV) diagram is shown in the figure
below for a system. The arrows of the curve indicate the direction
of the process and the points of interest are labelled. Calculate
the amount of work done on the system from 0 - 2 and then for the
entire curve 0 - 5 . The values for the points in the diagram
are:
Vo=25.8, V1= 19.9, V2=16.0, V3= 14.2, V4=14.2, V5= 7.85
P0=1.37E4, P1= 1.37E4, P2=5.76E3, P3= 5.76E3,...

In answering this set of nine questions, you are encouraged to
draw a PV diagram, with P (pressure) on the y axis and V (volume)
on the x axis. Plot the three points A, B, and C on this
diagram.
1. Consider 10.0 liters of an ideal (monatomic)
gas at a pressure of 33.0 atm and a temperature of
326 K. Call this state of the system A. Using the
ideal gas law, calculate the number of moles of gas...
