a 2.50mL sample of dry air in a cylinder exerts a pressure of3.00atm at room temperature. without changing the temperature, a piston is moved until the pressure in the cylinder is reduced to 1.00atm. what is the final volume of the gas?
P1 times V1 =P2 times V2
As you increase pressure you decrease volume
As you decrease pressure you increase volume.
