What decreases as as air heats up and increases as air cools?
Air pressure
How does the lava cool down when its in air?
Air at Earth's surface is much cooler than lava is, the lava will start to transfer heat to the air on contact. The air heats up and the lava cools down.
What is convection within the mantle responsible for?
As air heats, it becomes less dense and rises. As this hot air cools, it becomes more dense and falls. Winds are just convection currents. The air heats and rises, and the cool air rushes in to replace the air that rised. This air rushes in is near Earth's surface, so this is the wind.
What are sea breezes and why do they occur?
When the Sun rises over the land early in the morning, it heats the ground which in turn heats the air. Warmer air rises, and air from over the ocean is sucked in below it to replace all that air that rose. This air movement is called a sea breeze. In the evening, the Sun is on its way down, the ground cools and falls toward the ground, pushing the air from the ocean back out over the ocean. This air movement is also called a sea breeze.
What is thermal in flight?
Sunlight heats the ground, this warms the air which expands to reduced density, rises and creates a rising wind which fills your sails or lifts your wings
What decreases as air heats up and increases as air cools?
Air pressure
What increases as air heats up and decreases as air cools?
Air pressure
What decreases as as air heats up and increases as air cools?
Air pressure
Does lava cool down in the air?
No. Lava heats up the air. In turn, the air cools the lava.
Which heats up fastest soil water air or sand?
Soil heats up and cools down the fastest. Water heats up regulary and does not cool down for a while. Sand heats up the slowest and cools down the slowest.
What happens to air as it cools?
As air cools, the space it occupies becomes less. This results in an increase in density.
What happens when the air cools?
as air cools, the space it occupies becomes less. this result in an increas density
What happens to air temperature when it is compressed or allowed to expand?
Heats with compression, cools with expansion.
Explain the construction of an air conditioner?
it compresses a gas (freon or something like it), which heats the gas. Then it cools the gas (radiator grill on the outside) Then it lets the gas expand ... which cools the gas ... which cools the inside air.
Heat is to furnace as cool is to?
Air conditioner. One heats the interior of the house; the other cools it.
What happen to the volume and density of an air mass when it cools or warms?
it changes
Why air expands as it cools?
Air doesn't expand when it cools it contracts. any easy way to prove this point is to blow up a balloon put it in the fridge and leave it there for a while it will become smaller take it out of the fridge and it will get bigger again. Air expands as it heats and contracts as it cools.
