Task id16494

In an open vessel at temperature t1 = 17°C and relative humidity B1 = 80%, pressure pc1 = 1.01 105 Pa. The vessel was closed and cooled to a temperature t2 = 7°C. Find the relative humidity and pressure in the vessel. Saturated water vapor pressure at 17°C p1 = 1.9 103 Pa, at 7°C p2 = 0.99 103 Pa.
