Physics - Heat & Thermo Question with Solution | TestHub

A long container has air enclosed inside at room temperature and atmospheric pressure (10 ${}^5\mathrm{pa}$ ). It has a volume of $20,000\mathrm{cc}$. The area of cross section is $100{\mathrm{cm}}^2$ and force constant of spring is ${\mathrm{k}}_{\text{spring }}=1000\mathrm{N}/\mathrm{m}$. We push the right piston isothermally and slowly till it reaches the original position of the left piston which is movable. What is the final length of air column in cm ? Assume that spring is initially relaxed.
