2 cards from this section. Quick, good the night before a test.
What is the SI unit of pressure?
Think of how pressure is measured.
What happens to air pressure as we climb a mountain?
Consider the density of air at different heights.
What is air pressure caused by?
Think about what constitutes air.
True or False: Air pressure increases with altitude.
Visualize climbing a mountain.
How would the measurement of air pressure change if we moved from sea level to a mountain? Illustrate with real-life implications.
Consider applications in aviation and mountaineering.
Calculate how air pressure changes as you rise from sea level to 3000 meters, assuming air density decreases by 0.05 kg/m³ for every 500 meters.
Break this down into manageable steps, applying the formula P = ρgh at each altitude.
