4 cards from this section. Quick, good the night before a test.
What happens to air pressure as you go higher in altitude?
Think about the number of air molecules present at different heights.
What is the unit of air pressure?
How is pressure defined in terms of force and area?
What is the approximate air pressure at 1000 meters above sea level?
Recall the pressure values discussed in class.
True or False: Air pressure increases with altitude.
Think about how gravity affects air molecules.
Calculate the air pressure at an altitude of 3000 meters, assuming the density of air is still 1.225 kg/m³.
Plug in the values into the formula.
If you ascend from sea level to 5000 meters, calculate the drop in pressure compared to sea level.
Use the known pressure values at sea level and at 5000 meters.
