20-2 An ideal gas undergoes the thermodynamic process shown in the PV 2P, diagram in the figure. Determine whether each of the values (a) AU, (b)W, (c)Q for the gas is positive, negative, or zero. (Note that Wis the work done on the gas.) Hint: First use the ideal gas law to find the initial and final temperatures in terms of Po and Vo and determine if the final temperature is greater than, less than, or equal to the initial temperature. AU? W? Q? P A 2V₂

If we know that the internal energy of the monoatomic ideal gas remains constant during the process in B to C, what must be the pressure Pc at point C in terms of the original pressure P0.

T14f, please help me with my reviewer, I can’t get the answer for the step 2.

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?

A flexible box contains 5.60 grams of nitrogen gas (N2) which is maintained at a constant pressure of 1.35 x 10$ Pa. The box is placed over a fire, causing the volume to increase from 0.00200 m3 to 0.00300 m³. Find the increase in temperature of the gas. (For N2 molar mass M = 28 grams.)

Only part E required.

Consider ? = 5.00 mol of an ideal diatomic gas successively undergoing each one of the following thermodynamic processes:I. An adiabatic compression from an original volume of 0.150 m3to final volumeof 0.120 m3reaching a temperature of 293.0 K.II. An isothermal expansion to the original volume.III. An isochoric cooling to the original state. A) Draw a pressure-volume diagram showing all these processes.B) Calculate the pressure and temperature for each of the missing principal states.
