2. An ideal monatomic gas is at p. 3x10^5 n/m², Vo=0.060 m³ and T=27°C expands adiabatically up to pb=2x10^5 N/m². Vb = 0.085 m^3 and then isothermally to o= 0.100 m³   a) What are the temperature, pressure, and work done by the gas?   b) Show the processes on a p-V diagram.

The temperature of 5 moles of an ideal gas is 300 °C. How much work does the gas do in expanding isothermally to 4 times its initial volume? Given: ideal gas constant R = 8.31 J/(mol K) A.–3.3 x 102 J  B.+3.3 x 102 J C.–3.3 x 104 J  D.+3.3 x 104 J E.–3.3 x 106 J

1. An ideal diatomic gas at 63 K is slowly expanded adiabatically and reversibly to twice its original volume. What is its final temperature? Final temperature: K Think: Should the gas cool down or heat up during the adiabatic expansion? Does your answer validate your prediction.

A gas, initially at 22 degrees Celsius expands from 2.5 m^3 to 5 m^3 while keeping constant pressure of 10^5 Pa.  A) Sketch the PV diagram for this process B) Find the work done by the gas during this process C) What is the final temperature of the gas?

6 The diagram below depicts an ideal monatomic gas which is compressed isobarically at p = 1.05×10° Pa from state A (V₁ = 7.49×10 -3 m³) to state B (V₂ = 3.33×10 m³) where its temperature becomes T 3 B = 336°C. Its pressure is then increased at constant volume from state B to C and finally expanded isothermally until it returns to its initial state A. How much work is done by the gas and what is its temperature when it expanded during the isothermal process? с Pc B -A PA PB VB = VC VA The temperature of the gas during the isothermal process is 1370°C and the work done by the gas is 4105 kJ. The temperature of the gas during the isothermal process is 755.7 K and the work done by the gas is 2264 kJ. The temperature of the gas during the isothermal process is 1097°C and the work done by the gas is 6.375 kJ. The temperature of the gas during the isothermal process is 482.6 K and the work done by the gas is 2.834 kJ.

You would like to raise the temperature of an ideal gas from 295 K to 960 K in an adiabatic process. a)What compression ratio will do the job for a monatomic gas?  b)What compression ratio will do the job for a diatomic gas?
