pressure of gas

  2. 2. Free Powerpoint Templates Pressure of Gases•Pressure is determined by the flow of a mass from a high pressure region to a low pressure region. Pressure measurements are made on the fluid states- liquids and gases.
  3. 3. Free Powerpoint Templates What is Pressure? •Pressure is a force exerted by the substance per unit area on another substance. The pressure of a gas is the force that the gas exerts on the walls of its container. •Pressure is a property which determines the direction in which mass flows

  5. 5. Free Powerpoint Templates Pressure is defined a Force per unit area. With gases the force comes from the gas molecules hitting the side of the container. Air pressure is measured with a barometer.
  6. 6. Free Powerpoint Templates BAROMETER: •Pressure is directly measured with a device called a barometer. •Invented by Evangelista Torricelli (1608-1647), this mechanism operates similarly as a balance, using mercury as the standard weight.
  7. 7. Free Powerpoint Templates Boyle's Law •In 1662 Robert Boyle made the first systematic study of the relationship between volume and pressure in gases. .
  8. 8. Free Powerpoint Templates •Boyle's law or the pressure- volume law states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant. Boyle's Law
  9. 9. Free Powerpoint Templates Pressure and Boyle's Law •In the 17th Century, Robert Boyle first formulated the relationship among pressure, volume, and temperature as they related to gas through the formula: P1V1=P2V2P1V1=P2V2
