Asmooth vertical tibe having two differe...

Asmooth vertical tibe having two different sections, is open at both ends and equipped with two pistons of different areas. Each piston slides within a respective tube section. The pistons are tied with an inextensible weightless string. One mole of ideal gas is enclosed between them. The cross-section area of upper piston is `Delta A = 10 cm^(2)`greater than that of lower one. The combined mass of two piston is equal to `M = 5.0 kg`. The external pressure is `P_(0) = 1.0 atm`. By how much must the gas between the pistons the heated to shift pistons through `l = 5.0 cm`. `(1 atm = 1.0 xx 10^(5) Pa)`
