Question
Part B
Gas particles fill a container of any size.
Gas particles fill a container of any size.
The actual volume occupied by gas molecules is extremely small and can fit in a container of any size.
Part C
The volume occupied by a gas does not depend on what gas it is.
The attractive forces between the particles of a gas are very small and cannot hold the particles together. Particles of a gas move randomly and thus the distances between the particles are random values. The repulsive forces between the particles of a gas are very strong and the particles tend to be as far apart as possible.The actual volume occupied by gas molecules is extremely small and can fit in a container of any size.
Part C
The volume occupied by a gas does not depend on what gas it is.
Most of the volume of a gas is empty space. Gas particles are in constant motion, and the rate of this motion does not vary from one gas to another. The volume of a gas depend only on the path of motion of the particles. All gases have essentially the same size of particles.Explanation / Answer
Part-B: The attractive force is very less as compared to their kinetic energy and hence if you place even a small amount of gas in large volume container, the gas molecules are free to move in entire container and hence volume of gas= volume of container.So, first option is correct.
Part-C: As all the gas molecules are tiny and they are free to move in entire space of container, so all gases irrespective of their size of molecules, ocuppy the same volume (i.e. volume of container) and as they are too much freethere is considerable space between gas molecules whic are empty. So the most suitable is first option.
