Does the volume of particles affect the behavior of gas
lilavasa [31]

Answer:

Yes, it does, although only physically and not chemically.

Explanation:

If a volume of gas is way spread out, it won't collide with the other gas particles as often, reducing pressure and temperature because they lose kinetic energy to their surroundings when they don't collide.

If it is compressed, it increases temperature and pressure because the gas particles collide with each other and the walls of the container way more often than if they had more space.

Hope this answers your question.

P.S.

Fun fact, gas particles are actually moving at 300-400 meters per second at room temperature, they only slow down to walking speed at very low temperatures, like 10 Kelvin

what is the molarity of a 25 ml sample if it is diluted by adding 50 mol pf water and the molarity changes to 0.186 m?
Iteru [2.4K]

Answer:

0.558 M

Explanation:

Data obtained from the question. This includes the following:

Initial concentration (C1) =..?

Initial volume (V1) = 25mL

Final volume = 25 + 50 = 75mL

Final concentration (C2) = 0.186 M

The initial concentration of the solution can be obtained as follow:

C1V1 = C2V2

C1 x 25 = 0.186 x 75

Divide both side by 25

C1 = (0.186 x 75) /25

C1 = 0.558 M

Therefore, the initial concentration of the stock was 0.558 M
