Three moles of an ideal gas are compressed isothermally from $60 \mathrm{~L}$ to $20 \mathrm{~L}$ using constant pressure of $5 \mathrm{~atm}$. Heat exchange $\mathrm{Q}$ for the compression is - _________ Lit. atm.
Answer (integer)
200
Solution
<p>For isothermal process</p>
<p>$$\Rightarrow \begin{aligned}
& Q=-W \\
& Q=-5 \times 40 \\
& |Q|=+200 \text { Lit atm }
\end{aligned}$$</p>
