Pg tp-class17-air pressure wind

  1. 1. Air Pressure, Wind
  2. 2. Air that increases in temperature will 14% 86% 1. Increase in volume 2. Decrease in volume
  3. 3. What happened here??? The interior of the tank car was washed out & cleaned with steam. Then all the outlet valves were shut and the tank car was sealed. All the workers went home for the evening and when they returned, this is what they found.
  4. 4. Air that increases in temperature will 1. Increase in volume 2. Decrease in volume
  5. 5. Air that decreases in temperature will 1. Increase in volume 2. Decrease in volume
  6. 6. Pressure of a Gas = The force that a gas exerts on a certain area
  7. 7. Barometers
