Boyle's Law

Cards (15)

  • Robert Boyle - the English scientist who made accurate observations on the relationship of pressure and volume.
  • Boyle's law states that at a constant temperature, the volume of gas is inversely proportional to its pressure.
  • atm - the SI standard unit of pressure.
  • In the equation for Boyle's Law, P1 stands for: initial pressure
  • What is constant when using the Boyle's Law?
    Temperature
  • When pressure on a gas goes down, what happens to its volume?
    rises
  • In the equation for Boyle's Law, V2 stands for: final volume
  • What is the equivalent value of 1 atmosphere (1 atm) in Pascal(Pa)?
    101,325 Pa
  • A 2.75 L sample of dry air in a cylinder exerts a pressure of 3.00 atm at 30 °C. Without changing the temperature, a piston is moved until the pressure in the cylinder is reduced to 1.00 atm. What is the final volume of the gas?
    8.25 L
  • If the pressure of a confined gas is doubled while the temperature remains constant, what change would be observed in the volume?
    It would be half as large.
  • A gas at a pressure of 658 mm Hg is held in a container with a volume of 595 mL. The volume of the container is then increased to 1,065 mL without a change in temperature. What is the new pressure of the gas?
    368 mmHg
  • Two hundred twenty-five cubic centimeter (225 cm³) of a gas is contained in a vessel under a pressure of 800 mmHg. What would be the new volume of the gas if the pressure is changed to 1000 mmHg? Assume that the temperature remains constant.
    180cm³
  • What gas law does the graph shows?
    Boyle's Law
  • 1 atm - the standard pressure.
  • P1V1 = P2V2 - the mathematical statement of Boyle's Law.
