Physics - Heat & Thermo Question with Solution | TestHub

A monoatomic gas is heated from state 1 ($V=1$ L, $p=0.5$ atm) to the same final temperature by two straight-line paths on a $p$-$V$ diagram: to state 2 ($V=2$ L, $p=3$ atm) and to state 3 ($V=6$ L, $p=1$ atm). States 2 and 3 lie on one isotherm. How much more heat, in joules, does the path 1 to 3 need than the path 1 to 2? (1 L atm = $101.3$ J; one decimal.)
