Kinetic Theory ...

At what temperature will the rms speed of oxygen molecules become just sufficient for escaping form the Earth's atmosphere? (Given : mass of oxygen molecule $$\left( m \right) =2.76\times { 10 }^{ -26 }$$  kg, Boltzmann constant $$\left( { K }_{ B }=2.76\times { 10 }^{ -23 }{ JK }^{ -1 } \right) $$

One gram mole of helium at $$60C$$ is mixed with two gram moles of argon at $$30C$$ . The temperature of the mixture is 

Four litre of $${ CO }_{ 2 }$$ is kept at $$27^\circ C$$. What will be the volume if the temperature is lowered to 150 K at the same pressure.

According to kinetic theory of gases kinetic energy of gas molecules:

How much work to be done in decreasing the volume of an ideal gas by an amount of 2.4 x $$10^{-4} m^3$$ at constant normal pressure of 1 x $$10^5 N/m^2$$?

A flask breaks when pressure inside is 1.5 atmospheres. To what temperature can it be heated without breaking it if the initial pressure is atmospheric pressure at $$0C$$

19 gms of oxygen occupies 5 liters at 2 at. when the pressure is increased to 2.8 at. and the volume is reduced to 4 lit the percentage increase of temperature is .

One mole of gas occupies 10 ml at 50 mm pressure. The volume of 3 moles of the gas at 100 mm pressure and same temperature is 

The pressure of a given mass of gas is 100 cm at $${ 127 }^{ o }C$$ .The pressure of the same mass of gas having the same volume at $${ 27 }^{ o }C$$ is 

An open mounted bottle contains a gas at $${ 60 }^{ \circ  }$$C. What is the temperature to which the gas is to be heated so that 1/4 th mass of the gas may leave it.
