Question

A piston filled with 0.04 mol of an ideal gas expands reversibly from 50.0 mL to 375 mL at a constant temperature of ${37.0}^{o}C$. As it dos so, it absorbs 208 J of heat. The values of q and w for the process will be : (R = 8.314J/ molK)

Answer 1

Solution:-

As the heat is absorbed.

$\therefore q=+208J$

Now for reversible isothermal process,

$q=-W$

$\therefore W=-q=-208J$.

Hence the values of $q$ and $W$ for the process will be $+208J$ and $-208J$ respectively.
