If temperature (T) and amount of gas (n) remain constant, but pressure (P) and volume (V) change, then the ideal gas law: PV = nRT becomes
P1V1 = P2V2 --> (41)(16) = P2 (4)
--> P2 (4) = 656
P2 = 656/4 = 164 kPa
1,000 times larger! You're welcome :) All you do it divide the two. Hope this helped!
I’ve attached a photo with the definition and my answers
Hope this helps!
1620/ 5 is =324
To check just multiply
5 * 324
