That would probably depend on just how low the pressure is. If you're talking about any part of the world's natural environment, then the pressure is never too low for hot air to not rise.
However if you are talking about an extremely low pressure area, such as a vacuum, then the air would simply spread out to fill every possible crevice of the space instead of rising.

What does air do at the equator?
Mostly get hot and rise.
What happens to a barometer when a cold front comes in?
decreasing
Winds form in response to the?
Wind is caused from the way the radiation from the sun is absorbed by the surface of the Earth. The air is unevenly absorbed, which causes the hot air to rise and the colder air to sink. The air rising causes the pressure of the atmosphere to drop, the sinking of the air causes lower atmospheric pressure. Whenever the air moves from high to low pressure area, it creates wind.
Hot air rises cold air sink?
technically hot air does not really rise it is the cold air that sinks below it because it is more dense.
Do polar surface currents bring high or low temperatures?
high pressure region I Think i wrote a paper on it!
Why does a hot air balloon rise when the air inside it is heated up?
The hot pressure{air}builds up so the balloon goes up.
What kind of weather system is found in areas of high pressure Low air pressure?
Depending on the air pressure the weather system can be hot of cold
Does heat rise or hot air rise?
Heat is the energy of the hot air. Therefore hot air rises
Why does pressure in tires increase on hot days?
Because if you heat a gas (the air in the tyre) without letting it expand the pressure will rise.
In the atmosphere a hot air layer is found above a cold air layer How is the separation achieved and why does hot air always tend to rise?
It is because a hot air is a light matter while a cold air is a heavy matter of gas. Like, the difference of low(hot) pressure and high(cold) pressure area.
When does a air balloon rise?
A hot air balloon rises because when hot air is added it is intended to rise and when the hot air balloons wants to land, hot air is decreased.
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
What type of pressure is created when hot air rises?
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.
Does hot air rise or fall?
Hot air rises
Why do you think hot-air balloons can rise into the air?
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Why do hot air balloons rise with hot air?
Hot air is less dense than cooler air, therefore the balloon will rise (float) on the cooler air around it.
Will a balloon rise higher with hot air or cold air?
Hot air
