Derive the pressure of a liquid in a centrain depth.

Explain why Vapour pressure of a liquid is constant at constant temperature.

A manometer reads the pressure of a gas in an enclosure as shown in Fig. 10.25 (a) When a pump removes some of the gas, the manometer reads as in Fig. 10.25 (b) The liquid used in the manometers is mercury and the atmospheric pressure is 76 cm of mercury. (a) Give the absolute and gauge pressure of the gas in the enclosure for cases with mercury)

What is capillarity? Derive an expression for the ascent of liquid in a capillary.

Derive the expression of escape speed.

Show that the pressure at a point in a liquid is directly proportional to the depth of the point from the surface.

100 g of liquid A (molar mass 140 g mol^-1) was dissolved in 1000g of liquid B (molar mass 180 g mol^-1) . The vapour pressure of pure liquid B was found to be 500 torr: Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is 475 Torr.

With the help of Raoult's law show that total vapour pressure of a binary liquid solution varies linearly with the mole fraction of a component.

Explain why Vapour pressure of a liquid decreases when a non-volatile solute is added to it.

Heptane and Octane form an ideal solution at 373K the vapour pressure of the pure liquids at this temperature are 105.2 kPa respectively. If the solution contains 25g of heptane and 28.5g octane, calculate Vapour pressure exerted by heptane
