# filling of a ballon and gas law [closed]

When we fill a balloon with gas the pressure and volume inside it increases. Will this not go against the gas law as pressure and temperature are inversely proportional to each other.

• The said law is applicable if we have constant amount of gas. – Ivan Neretin May 3 '17 at 10:05
• @Ivan You mean the OP's interpretation of the law? Glorfindel's answer seems plausible, yet he doesn't "pin-down" one of the parameters in the Ideal gas law. [Side note: Why on earth do you keep away from The Periodic Table? It'll be interesting to have you there ;) ] – paracetamol May 3 '17 at 11:01
• @paracetamol I mean Boyle's law, not the full PV=nRT thing. What is The Periodic Table? – Ivan Neretin May 3 '17 at 11:12

$$PV = nRT$$
You're right that the left hand side (pressure times volume) increases, but so does $n$, the amount of substance of gas. So the ideal gas law is still satisfied.
