A metal cylinder contains 1 mol of nitrogen gas at STP. What will happen to the pressure if
tiny-mole [99]

Answer:

Then pressure will double

Explanation:

PV = nRT

P = nRT / V

If all other variables are kept constant, P will be proportional to n i.e

P1 / n1 = P2 / n2

n = 1

P1 = P

n2 = 2

P2 =?

P1 / n1 = P2 / n2

P /1 = P2/2

Cross multiply

P2 = 2P

Therefore, if an additional 1mole of the gas is added, the pressure will double
