Presentation Transcript

  1. Pressure

  2. Pressure

  3. Pressure force applied OVER an area

  4. Measuring Pressure

  5. Barometers the measure ATMOSPHERIC pressure

  6. Manometers measure the pressure an of ENCLOSED gas vacuum BEFORE AFTER

  7. Pressure Units atmospheres (atm) kilopascals (kPa) millimeters of mercury (mm Hg) pounds per square inch (psi) Torricelli units (torr)

  8. STP standard TEMPERATURE 273 K and PRESSURE 1 atm

  9. Conversions • 1 atm • 760 mm Hg • 101.3 kPa • 14.7 psi • 760 torr

  10. Pressure Practice • 1) Convert 125 mmHg to atmospheres.

  11. Pressure Practice • 2) Convert 3.20 atm to kilopascals.

  12. Pressure Practice • 3) Convert 5.38 kPa to millimeters of mercury.

  13. Pressure Practice • 4) Convert 459.33 torr to Pascals.

  14. Pressure Practice • 5) Convert 45 atm to mmHg.

  15. Pressure Practice • 6) Convert 302.0 kPa to mmHg.

  16. Pressure Practice • 7) Convert 765 mmHg to kPa.

  17. Pressure Practice • 8) Convert 25.0 atm to kPa.

  18. Pressure Practice • 9) Convert 901 mmHg to atm.

  19. Pressure Practice • 10) Convert 345 kPa to atm.
