## Monoatomic Gas

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### Monoatomic Gas

Does a monoatomic ideal gas indicate constant pressure or constant temperature?

### Re: Monoatomic Gas

It depends? A monoatomic ideal gas can be at constant T or constant P.

### Re: Monoatomic Gas

I believe Lavelle once said in class before a test or the midterm to assume all gases are monoatomic unless told otherwise, is this still true for the final ?

### Re: Monoatomic Gas

A monoatomic ideal gas can be under conditions of constant T, constant P, and/or constant V, depending on the system presented to you. A monoatomic ideal gas is just an ideal gas (obeys PV = nRT) which has only 1 atom (Ne (g), Ar (g), etc.)

Hope this helps! :)
