Question

Which sequence describes the result of increasing the number of gas particles in a container? A.) fewer collisions --> lower collision force --> lower pressure B.)more collisions --> lower collision force --> lower pressure. C.) fewer collisions --> greater collision force -->higher pressure. D.)more collisions --> greater collision force --> higher pressure

Answer 1

I believe the correct response is D. More collisions that result in greater collision force and higher pressure.

Answer 2

Answer: Option (D) is the correct answer.

Explanation:

It is known that relation between pressure and force is that, pressure equals force divided by area.

Mathematically,      P = $\frac{F}{a}$

where              P = pressure

                        F = force

                        a = area

Hence, when there is increase in number of gas particles in a container the there will be more number of collisions due to increase in number of particles. This will lead to greater collision force and as a result there will be increase in pressure because force is directly proportional to pressure.

Thus, we can conclude that the sequence more collisions --> greater collision force --> higher pressure best describes the result of increasing the number of gas particles in a container best describes the result of increasing the number of gas particles in a container.
