Question

When dealing with 1 liter of Argon as a closed system and as an ideal gas that undergoes an isothermal expansion, which of the following expressions can be used to describe the state of your thermodynamic system? Group of answer choices a. PV = R. b. PV = const. c. P is inverse proportional to V. d. Answers (a) and (b) are both correct and they give the same information about the system under investigation. e. Answers (b) and (c) are both correct and they give the same information about the system under investigation.

Answer 1

Answer:

e.Answers (b) and (c) are both correct and they give the same information about the system under investigation.

Explanation:

Given that

System is closed and gas is expand at constant pressure.

We know that in constant pressure process the temperature of gas remains constant but pressure and volume of gas changes.

In expansion process volume of gas will increases and the pressure of gas will decreases.

At constant temperature for ideal gas

P V = m R T

m ,R and T is constant then

P V= Constant

P V =C

From above we can say that pressure is inverse to the volume.

$P=V^{-1}C$

So option b and c both are correct.

It means that option e is correct.
