A vertical cylinder closed from both ends is equipped with an easily moving piston dividing the volume into two parts, each containing one mole of air. In equilibrium at `T_0 = 300 K` the volume of the upper part is `eta = 4.0` times greater than that of the lower part. At what temperature will the ratio of these volumes be equal to `eta' = 3.0` ?

Explanation

`T=T_(0)eta’(eta^(2)-1)//eta(eta’^(2)-1)`
