Chapter 18: Problem 7

A quasi-static process begins and ends at the same temperature. Is the process necessarily isothermal?

Short Answer

Expert verified
No, a quasi-static process that begins and ends at the same temperature is not necessarily isothermal.

Step by step solution

01

Understanding Definitions

Firstly, note what a quasi-static process and an isothermal process mean. A quasi-static process is one that occurs in such a slow manner that at each moment during the process, the system can be considered to be in a state of equilibrium. An isothermal process is a process in which the system's temperature remains constant.
02

Consider Possible Scenarios of Quasi-static Processes

Quasi-static processes can proceed in various ways. For example, they could involve changes in volume or pressure, but they don't necessarily have to involve an isothermal process.
03

Judgment

Just because a process is quasi-static and it begins and ends at the same temperature does not necessarily mean it was at the same temperature at all points during the process. Therefore, a quasi-static process is not necessarily isothermal, even if it starts and ends at the same temperature.

Three identical gas-cylinder systems are compressed from the same initial state to final states that have the same volume, one isothermally, one adiabatically, and one isobarically. Which system has the most work done on it? The least?

Experimental studies show that the \(p V\) curve for a frog's lung can be approximated by \(p=10 v^{3}-67 v^{2}+220 v,\) with \(v\) in \(\mathrm{mL}\) and \(p\) in \(\mathrm{Pa}\). Find the work done when such a lung inflates from zero to \(4.5 \mathrm{mL}\) volume.

Does the first law of thermodynamics apply to irreversible processes?

In a reversible process, a volume of air \(V_{0}=17 \mathrm{m}^{3}\) at pressure \(p_{0}=1.0\) atm is compressed such that the pressure and volume are related by \(\left(p / p_{0}\right)^{-2}=V / V_{0} .\) How much work is done by the gas in reaching a final pressure of 1.4 atm?

How much of a triatomic gas with \(C_{V}=3 R\) would you have to add to 10 mol of monatomic gas to get a mixture whose thermodynamic behavior was like that of a diatomic gas?
