A container with insulating walls is divided into two equal parts by a partition fitted with a value. One part is filled with an ideal gas at a pressure and temperature , whereas the other part is completely evacuated. If the valve is suddenly opened, the pressure and temperature of the gas will be
2.
Molecular motion shows itself as
3.
A box contains molecules of a gas. How will the pressure of the gas be effected, if the number of molecules is made
4.
Root mean square velocity of a particle is at pressure If pressure is increased two times, then the velocity becomes
5.
The amount of heat required to convert 10 g of ice at into steam at 100 is (in calories)
6.
Air inside a closed container is saturated with water vapour. The air pressure is and the saturated vapour pressure of water is . If the mixture is compressed to one half of its volume by maintaining temperature constant, the pressure becomes
7.
If temperature of gas increases from to the will be
8.
The speed of gas molecules is given by
9.
The temperature of 5 moles of a gas at constant volume is changed from 100 to 120. The change in internal energy is 80 J. the total heat capacity of the gas at constant volume will be in is
10.
Consider a collection of a large number of particles each with speed The direction of velocity is randomly distributed in the collection. What is the magnitude of the relative velocity between a pairs in the collection
