• Atmospheric pressure: Weather

  (Hint: discuss the differences in high pressure and low pressure systems. How does each affect the local and regional weather? How is air affected by air pressure?)

• Design of a cylindrical, pressurized water tank

  The pressure at the surface of the water will be 105 kPa, and the depth of the water will be 13.9 m. The pressure of the air in the building outside the tank will be 90.0 kPa. 1.

• Pressure difference between atmosphere and an evacuated tank.

  Air at atmospheric pressure and 300K will be allowed to enter the turban inlet, while the pressure drop between the atmosphere and the tank serves to operate the turbine driven grinder.

• Tire pressure and temperature problem

• Pressure Cooker

  Assume that the temperature of the air outside the pressure cooker is 20 degrees Celsius (room temperature) and that the area of the pressure cooker lid is A. Take atmospheric pressure to be p_a.

• Groundhogs know physics!! They ventilate their burrows by bu

  This difference in air pressure will move air in at the ground level entrance and out at the mound entrance.

• Pressure, Volume and Temperature

  42637 Pressure, Volume and Temperature Fill an empty 2 liter bottle 1/3 full with the hottest tap water you can get. Immediately screw the cap on. Set the bottle aside and let it cool. The side buckles. Why?

• Physical science: briefly explain how air temperature, pressure, and density are related to cloud formation.

  As air rises, there is less and less air above it, thus reducing the pressure that is placed on the rising air. This lower pressure on the molecules of water and gases in air causes the air to expand and lose density.

• Carbonation and Solubility of Carbon Dioxide (CO2) in Water

  Air pressure changes with elevation. At higher elevations, there is less air pressure because there is less air pushing down. At lower elevations, there is more air pressure because there is more air pushing down.
