How are air sacs used for gas exchange? What does air pressure affect? How does air pressure affect evaporation? What happens when the pressure of a gas is lowered? Explain how cold air can have less pressure (less collisions) and more density. ...
Why does evaporation increase the density of ocean water? What causes evaporation in the water cycle? How does evaporation purify water? Why does air have pressure? Why is evaporation useful? How can air masses affect air pollution? How does temperature affect air currents?
Lesson 2: Temperature, Pressure, and Humidity. Temperature and Pressure Air is made up of molecules that are constantly moving. As air warms up, these. 1 ATMOSPHERIC PRESSURE & DENSITY. 2 The denser the atmosphere… the greater its weight, and the greater its air pressure. Essenti...
Density is the amount of matter (mass) in a given space (volume) For example, a golf ball and a table-tennis ball have similar volumes. But a golf ball has more mass than a table-tennis ball does. So, the golf ball has a greater density. Instructional Approach(s): The teacher shoul...
Flying textbooks list the critical factors that affect lift (speed, wing area, air density, ….) ; none of these factors include the low air pressure on the top of the wing. Yeah I know, the same textbook will contradict itself and say that lift is caused by low air pressure on the ...
How does temperature affect the kinetic energy of gas molecules? Kinetic Theory of Gases: The Kinetic Theory of Gases is a simple model that relates microscopic properties (such as average speed) of molecules to macroscopic properties (such as pressure or temperature) of gases based on the assump...
1. Improve the Quality of the Air IntakeAir quality affects how your system functions. Three components of the air compression system influence performance:Temperature: The temperature of the intake air determines air density. Cool air requires less energy to compress, making it far more efficient ...
It does a great job of explaining the very basic reason why the plane flies, but as soon as you want any more details, you get stuck. It does not say anything about pressure distributions, and it's not really clear how much air you should consider to be deflected by the wing. I ...
How does heating air affect its density and pressure? How does intrapleural pressure change during inspiration? What would happen without hydrostatic equilibrium? Why does air have pressure? Why does the atmospheric pressure decrease with altitude?
How do air currents differ in pressure? How do air currents affect heat in the Earth's atmosphere? Why is the mesosphere colder than the troposphere? Why does cold air sink? How do jet streams affect air masses? Why is density important as a property of matter?
