The gas in a cylinder has a volume of 7 liters at a pressure of 103 kPa. The pressure of the gas is increased to 219 kPa. Assuming the temperature remains constant, what would the new volume be?

Question

I know this is chemistry but no one is active on chemistry so I had to post it here.

welshfella · Answer

As the pressure increases  the volume will decrease proportionally.

welshfella · Answer

P1 * V1 = P2 * V2

solve for V2

welshfella · Answer

here V1 = 7 , P1 = 103 and P2 = 219

welshfella · Answer

If i remember correctly this is Boyle's law.

saeedd · Answer

@welshfella so It would be 103 X 7 = 219 X V2

saeedd · Answer

@welshfella so 4L?

welshfella · Answer

your equation is correct but  its not 4 L

welshfella · Answer

you need to divide both sides of the equation by 219.
