2 cards from this section. Quick, good the night before a test.
What happens to air pressure inside your lungs when you inhale?
Consider the relationship between the diaphragm's position and lung volume.
What type of weather does a high-pressure system usually bring?
Think about what occurs when air is pushed down.
What effect does a high-pressure system have on weather?
Think about how air is moving in a high-pressure zone.
True or False: Low-pressure systems are generally associated with good weather.
Remember what happens when air pressure lowers.
Given a mercury barometer shows a column height of 760 mm, calculate the air pressure in Pascals. Use the density of mercury (13600 kg/m³) and gravitational acceleration (9.8 m/s²).
Convert mm to meters when applying the formula.
If air pressure at sea level is approximately 101325 Pa, how does the pressure change with altitude to 3000 meters? Assume constant air density of 1.225 kg/m³.
Use the same pressure formula but adjust the height for altitude.
