Question
A sample of $n$ moles of an ideal gas undergoes an isothermal expansion. Find the heat flow into the gas in terms of the initial and final volumes and the temperature.
Step 1
This implies that the change in internal energy of the gas is also zero, since the internal energy of an ideal gas depends only on its temperature. Mathematically, this can be written as: \[ \Delta U = 0 \] Show more…

One mole of an ideal gas undergoes an isothermal expansion. Find the thermal energy $Q$ added to the gas in terms of the initial and final volumes and the temperature. (Hint: Use the first law of thermodynamics.)
Let $n$ Moles Let $n$ moles of an ideal gas expand adiabatically from an initial temperature $T_{1}$ to a final temperature $T_{2}$. Prove that the work done by the gas is $n C_{V}\left(T_{1}-T_{2}\right)$, where $C_{V}$ is the molar specific heat at constant volume. (Hint: Use the first law of thermodynamics)
A sample consists of an amount $n$ in moles of a monatomic ideal gas. The gas expands adiabatically, with work $W$ done on it. (Work $W$ is a negative number.) The initial temperature and pressure of the gas are $T_{i}$ and $P_{r}$ Calculate (a) the final temperature and (b) the final pressure.
