Calculate the capillary rise of water in tube of 2mm bore.

Calculate the mass of : 1 molecule of water

Vapour pressure of water at 293 K is 17.535 mm Hg. Calculate the vapour pressure of water at 293 K when 25 g of glucose is dissolved in 450 g of water.

What will be the rise of water when a capillary tube of radius 0.5mm is dipped iri water?

What should be the maximum average velocity of water in a tube of diameter 2 cm so that the flow is laminar? Viscosity of water is 10^3 Ns m^(-2) .

What do you mean by relative lowering of vapour pressure? Calculate the relative lowering of Vapour pressure of a solution formed by dissolving 50 g of urea (NH_2 CONH_2) in 850g of water.(Given vapour pressure of pure water at 298K= 23.8mm of Hg.)
