Задача id16196

In a narrow cylindrical tube, sealed at one end, there is air separated from the outside space by a column of mercury with a length of h = 15 cm. When the tube lies horizontally, the air occupies a volume V1 = 240 mm3 in it; when the tube is installed vertically, with the open end up, the air occupies a volume V2 = 200 mm3. Determine the atmospheric pressure P0 (Fig.).
