Methane, a highly flammable gas, is placed in a piston that has a volume of 2.1
kupik [55]
Use the formula:
P1V1/T1N1 = P2V2/T2N2
You can cross out T1,N1,T2, and N2 because you are working with pressure and volume in this equation.
Now, you are left with Boyle’s Law:
P1V1 = P2V2
Substitute the values in
STP = 1 atm for pressure
(1 atm)(2.1L) = P2 (0.125 L) [I converted 125 ml to liters so they would be the same unit]
Now, divide both sides by 0.125 to find P2
P2 = (1 atm)(2.1 L)/(0.125 L)
Liters cancel out
P2 = 16.8 atm

I Need Help!!!
borishaifa [10]

Answer:

I think that temperature will be cut in half.

When volume increases, pressure decreases. As pressure decreases, temperature decreases. So if you double volume, pressure is halved and so will the temperature. I'm new to this, but I think that's the answer . Tell me if I'm right good luck!
