Get started for freeQuestion: (II) A 1.0-L volume of air initially at 3.5 atm of (gauge) pressure is allowed to expand isothermally until the pressure is 1.0 atm. It is then compressed at constant pressure to its initial volume, and lastly is brought back to its original pressure by heating at constant volume. Draw the process on a PV diagram, including numbers and labels for the axes.
Question: Which is possible: converting (i) 100 J of work entirely into 100 J of heat, (ii) 100 J of heat entirely into 100 J of work?
(a) Only (i) is possible.
(b) Only (ii) is possible.
(c) Both (i) and (ii) are possible.
(d) Neither (i) nor (ii) is possible.
Question: An ideal gas undergoes an isobaric compression and then an isovolumetric process that brings it back to its initial temperature. Had the gas undergone one isothermal process instead,
(a) the work done on the gas would be the same.
(b) the work done on the gas would be less.
(c) the work done on the gas would be greater.
(d) Need to know the temperature of the isothermal process.
(I) An ideal gas expands isothermally, performing
Calculate the work done by an ideal gas while going from state A to state C in Fig. 15โ28 for each of the following processes:
(a) ADC,
(b) ABC, and
(c) AC directly.
