Kinetic Theory ...

A vessel is filled with an ideal gas at a pressure of 10 atmospheres and temp 27$$^{0}$$C . Half of the mass of the gas is removed from the vessel & the temp. of the remaining gas is increased to 87$$^{0}$$C . Then the pressure of the gas in the vessel will be

2 grams of monoatomic gas occupies a volume of 2 litres at a pressure of $$8.3\times 10^{5}Pa$$ and 127$$^{0}$$C . Find the molecular weight of the gas. (R=8.3 joule/mole/K)

From a disc of radius $$R$$ and mass $$M$$, a circular hole of diameter $$R$$, whose rim passes through the centre is cut. What is the moment of inertia of the remaining part of the disc about a perpendicular axis, passing through the centre?

A reciever has a pressure of 144cm of Hg. After two strokes with an exhaust pump, the pressure is 36cm of Hg. After another two strokes the pressure will be.

Three flasks of identical volume are filled separately by 

(a) 1 gram of $$H_{2}$$ 

(b) 1 gram of $$O_{2}$$ 

(c) 1 gram of $$CO_{2}$$

They are immersed in a tank of water so that all of them attain same temperature. The pressures $$P_{1},P_{2}$$ and $$P_{3}$$ have the on.

A closed copper vessel contains water equal to half of its volume when the temperature. Of the vessel is raised to 447$$^{0}$$c the pressure of steam in the vessel is (Treat steam as an ideal gas, R=8310 J/k / mole, density of water =1000 kg/m$$^{3}$$ molecular weight of water =18 )

A sample of $$O_{2}$$ gas and a sample of hydrogen gas both have the same no. of moles, the same volume and same pressure. Assuming them to be perfect gases, the ratio of temperature of oxygen gas to the temperature of hydrogen gas is :

The density of a gas at N.T.P. is 1.5gm/lit. its density at a pressure of 152cm of Hg and temperature 27$$^{0}$$ C

An electric bulb of $$250cc$$ was sealed off at a pressure $$10^{-3}$$ mm of Hg and temperature $$27^{0}$$ C. The number of molecules present in the gas is

Two identical containers connected by a fine capillary tube contain air at N.T.P. if one of those containers is immersed in pure water, boilling under normal pressure then new pressure is
