Acontainer with a specific volume “v” changes to “2v.” what happens to the average distance between gas molecules? assume that pressure and temperature of the gas remain constant.

Explanation:

It is given that the volume is changing from V to 2V whereas both pressure and temperature remains the same.

So, this also means that number of moles of the substance remains the same but only change in volume is occurring. Therefore, greater volume of container will lead to more space for the movement of molecules.

As a result, molecules will start to move away from each other. Hence, space between them will increase.

Thus, we can conclude that the average distance between gas molecules will increase.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
