Hot air expands, and if in an enclosed space, will cause high pressure. If not enclosed, the hot air will "spread out". As a result, you would have less hot air in a given space than cold air filling an identical space. It is that question of density which makes hot air rise.

∙ 10y agoIf this is about weather, then high pressure is usually related to fine and warm weather.
If this is about engineering, then anything goes.
When air is compressed, it gets hot, but eventually it'll cool off and then you'll have high pressure and low temperature.

High pressure areas are created around the poles as cold air?
It RISES...
How does a low pressure area is created?
The Low Pressure Area is formed in the bodies of water like oceans and sea, therefore it is being created by the pressure given up by the water which produces a large pressure of air that can lead to typhoons.
Is air rising or sinking at low pressure belts?
Air usually rises at low pressure areas
Does air pressure affect earths weather?
It expands, rises, and becomes less dense.
Why is air pressure at the top of a chimney less than air pressure at the bottom?
Smoke rises up the chimney partly because hot air rises and partly because it is pushed wind blowing across the top of a chimney lowers the air pressure there the higher pressure at the bottom pushes air and smoke up the chimney
High pressure areas are created around the poles as cold air?
It RISES...
What is the air pressure inside a cyclone?
the air in the cyclone rises as the air rises it cools
What air pressure is formed when warm air rises?
Low pressure
How Does temperature affect air pressure and air density?
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.
How does temperature affect air density and air pressure?
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.
What does high air pressure?
air pressure is the amount of air pushing down on you and high pressure is air that rises.
What warm air rises what is created in the void?
There is no void because the reduced pressure brings in iar from surrounding areas.
Why is air pressure at the top of a chimney less tan air pressure at the bottom?
Hot air rises
What When warm air rises what is created in the void?
There is no void because the reduced pressure brings in iar from surrounding areas.
What happens to air at the center of a cyclone or center of low pressure?
What is the center of low air pressure
