Question

How is the volume of a gas related to its concentration of particles?
A) As the volume of a contained gas expands, its pressure concentration of particles will increase.
B) As the volume of a contained gas extends, its pressure concentration of particles will increase.
C) As the volume of a contained gas decreases, its pressure concentration of particles will increase.
D) As the volume of a contained gas compresses, its pressure concentration of particles will decrease.

Answer 1

The Answer is: C

Because of the volume that is already set by the size and weight of the container. In other words the gas is pushing all particles out of the way and replacing its self therefore the pressure increases.

Answer 2

Answer: C) As the volume of a contained gas decreases, its pressure concentration of particles will increase.

Explanation:

We know that the particles of gas are continuously moving and have negligible force of attraction. So they are able to spread all over in the container in which they are contained .

Also, because of so much space between them , they highly compressible .

There is inversely proportional relationship between the volume and the pressure of a gas.

Thus when the volume of a contained gas decreases, its pressure concentration of particles will increase.
