Law of conservation of momentum states that
For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed.

Law of Conservation of Momentum Examples

Following are the examples of law of conversation of momentum:

Air filled balloons
System of gun and bullet
Motion of rockets

What is the process for the liquification of gas

Posted by Raman Preet Kaur 6 years, 2 months ago

CBSE > Class 11 > Physics

2 answers

Yogita Ingle 6 years, 2 months ago

A gas can be converted into a liquid through a process called liquefaction.

Liquefaction of a gas can occur only when the intermolecular force of attraction between the gas molecules are increased.

Methods for liquefaction:

(i) Increase in pressure of the gas at room temperature: On increasing pressure the gas molecules come closer to each other, results in an increase in the intermolecular forces of attraction between the molecules, which leads to the liquefaction of gases.

(ii) Decrease in the temperature of the gas:

As the gas gets cooled the kinetic energy of the gas molecules decreases, results in the decrease of the speed of their random motion and in the increase of the force of attraction between them.

Carbon dioxide, ammonia, sulphur dioxide and hydrogen chloride can be liquefied by increasing the pressure and decreasing the temperature.

There are some gases, which cannot be liquefied at room temperature even at very high pressure. These gases are called as permanent gases.

Ex: H_2, He, O₂.

Srishti ? 6 years, 2 months ago

Liquefaction of gases is the process by which substances in their gaseous state are converted to the liquid state. When pressure on a gas is increased, its molecules closer together, and its temperature is reduced, which removes enough energy to make it change from the gaseous to the liquid state.

Newton 1 law:it states that a body continues to be in state of rest or motion or in same direction unless and untill an external force is applied on it. It is also caled law of inertia Newton 2 law :the force acting on body is directly proportional to rate of change of linear momentum F=ma where m is mass and a is acceleration

What is the range of nuclear force'

Posted by Arjun Thakur & Manju Thakur 6 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Sia ? 6 years, 2 months ago

The range of the nuclear force is short, only a few femtometer (1 fm =10−15 m), beyond which it decreases rapidly. That is why, in spite of its enormous strength, we do not feel anything of this force on the atomic scale or in everyday life. The development of a proper theory of nuclear forces has occupied the minds of some of the brightest physicists for seven decades and has been one of the main topics of physics research in the 20th century.
