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.

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.

answer; ///i do believe that the correct answer is (c) hold atoms together to form compound;

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.
