Question: A smooth vertical tube having two different sections is open from both ends and equipped with two pistons of different areas (Fig. 2.i). Each piston

A smooth vertical tube having two different sections is open from both ends and equipped with two pistons of different areas (Fig. 2.i). Each piston slides within a respective tube section. One mole of ideal gas is enclosed between the pistons tied with a non-stretchable thread. The cross-sectional area of the upper piston is ΔS = 10 cm2 greater than that of the lower one. The combined mass of the two pistons is equal to m = 5.0 kg. The outside air pressure is P0 = i.0 atm. By how many kelvins must the gas between the pistons be heated to shift the pistons through l = 5.0 cm?
