How much will be change P if
A) volume reduced to 1.5 ,2 and 2.5
B) volume increase to 1.5 ,2 and 2.5
Is this Boyle's law?
So figure out the constant (P1V1)
Now that is the actual pressure. Your question asks what will be change P. I don't know what that means. Change is normally P2-P1, but for the life of me I don't know why a competent teacher would find that. Now you teacher might have had in mind the ratio, P2/P1, but I just don't know.
The best I can do is help you find the new pressure, as above.
