A gas sample is help at a constant temperature, Whay happens to the pressure of the sample if the volume is doubled and the number of molecules is doubled ?

Nothing  

Explanation:

To solve this problem, we can use the Combined Gas Laws:

Data:

p₁ = p₁; V₁ =   V₁; n₁ =      n₁; T₁  = T₁

p₂ = ?;   V₂ = 2V₁; n₂ = 2n₁; T₂ =  T₁

Calculation:

1 a

2 d

3 a

4 c

explanation:

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
