25. ssm A monatomic ideal gas has an initial temperature of 405 K. This gas expands and does the same amount of work whether the expansion is adiabatic or isothermal. When the expansion is adiabatic, the final tem- perature of the gas is 245 K. What is the ratio of the final to the initial volume when the expansion is isothermal?

Question B: A sample of 1.00 mole of a diatomic ideal gas is initially at temperature 265 K and volume 0.200 m3. The gas first undergoes an isobaric expansion, such that its temperature increases by 110.0 K. It then undergoes an adiabatic expansion so that its final volume is 0,440 m3. i. Sketch a PV diagram for the two-step process, including labeled initial, final, and intermediate states, and a two-part curve/path with an arrow indicating direction. Label the initial state "i", the final state "f", and the intermediate state "b". Write down the known values for P, T, and V at each point, e.g. T; = 265 K, and Th = 375 K.

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?

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.
