An engine consists of a constant volume process at 0.8 m3 from 136 kPa to 381 kPa, an isothermal expansion until the pressure drops to its original value, and a constant pressure process returning to its original pressure and volume. Calculate the efficiency of this process if the gas is ideal and diatomic. [Hints: 1. You need the volume at the end of the isothermal process. Find it easily with the ideal gas law! 2. For |QHl, add the energy inputs during the constant volume and iosthermal processes.]

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.

Question

An engine consists of a constant volume process at 0.8 m3 from 136 kPa to 381 kPa,
an isothermal expansion until the pressure drops to its original value, and a constant
pressure process returning to its original pressure and volume. Calculate the efficiency
of this process if the gas is ideal and diatomic.
[Hints: 1. You need the volume at the end of the isothermal process. Find it easily with
the ideal gas law! 2. For |QHl, add the energy inputs during the constant volume and
iosthermal processes.]

Consider 2 moles of an ideal monatomic gas at 350 K and 1 atm. First, let the gas expand isothermally and reversibly to twice the initial volume; Second, let this be followed by an isentropic expansion from twice to four times the initial volume. a) How ch heat (in added to the gas in each of these two processes? b) What is the temperature at the end of the 2nd process? c) suppose the 1st process is replaced by an irreversible expansion, into a vacuum, to a total volume twice the initial volume. What is the increase of entropy in the irreversible expansion (in J/K)?
