Pressure
What do you use to measure pressure?
Barometer
Color of can which absorbed and released heat fastest
black can
Weather and planes
Troposphere
Capacity is the amount of _ that the air can hold at one time
What is water vapor
Usual starting air temperature in lab according to Celsius
21 degrees
What is the relationship between pressure and temperature?
As temperature increases, pressure decreases
As temperature decreases, pressure increases
Substance that changed temperature the most slowly
water
Layers in which temp decreases
troposphere and mesosphere
When the air is _ more water can be held in the air
What is warmer
Temperature is measured in Fahrenheit, Celsius, and this extreme unit
What is Kelvin
What made the water rise?
Atmospheric pressure pushed water towards the low pressure region caused by the warm air
The proper name for a wet bulb/dry bulb device
Psychrometer
coldest temp, meteors
mesosphere
This type of humidity compared to the temperature and capacity of an air mass is measured in percent and called this
Relative humidity
Colder temperature makes it so air can hold less water this causes _______ as warm air cools down
Condensation
What is the major cause for all wind?
Air movement from high pressure to low pressure
The purpose of chilling the water to dew point
To find the absolute humidity of the air, which would be the same as the capacity at dew point.
northern lights, satellites
thermosphere
The actual mass of water in the air by volume or mass.
Absolute Humidity
Why should you hold the thermometer by the stem?
Temp is measured at the bulb
Explain the two reasons for wind movement on a global scale.
Convection cells - air moves towards or away from the equator as hot air rises and cold air sings.
Coriolis Effect - winds curve around the earth due to the earth's rotation
What is a hygrometer?
Something to measure humidity.
Absorbs UV Rays, protecting us
Stratosphere
The point at which water vapor condenses into a liquid is called this
What is dew point
What is temperature?
A measure of the average movement of molecules
