What is true awarm is less dense than cooler air bwarm air is as dense as cooler air cwarm air has no density dwarm air denser than cool air?
Warm air is less dense than cooler air.
Why hydrogen balloon rise in air?
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
Why a balloon filled with hydrogen gas floats in air?
bcoz hydrogen gas is less denser than air and is exerts buoyant force on balloon
What element is denser than air?
Lots of things are denser than air. Mercury for example.
Should weather balloons be filled with hydrogen?
Yes, hydrogen is lighter than air and so causes the balloon to float.
What happens if the ground is cooler than the air?
When the ground is cooler than the air you get fog.
What is true awarm is less dense than cooler air bwarm air is as dense as cooler air cwarm air has no density dwarm air denser than cool air?
Warm air is less dense than cooler air.
Why does water feel cooler than air at the same temperature?
Evaporation of water is a process with heat absorption.
What percentage of hydrogen is lighter than air?
100% of hydrogen is lighter than air
How do you think the density of heated air compares to the density of cooler air?
The density of heated air is less than the density of cooler air.
Why does hydrogen rise in air?
this happens because hydrogen is lighter than air
Why do hot air raise?
Because it is lighter than cooler air.
Why does a hydrogen filled in balloon rise?
beecause hydrogen is less dense and light then air , easy to fly..the hydrogen in the balloon is lighter than the air outside of it.density of hydrogen is lower than air
Why hydrogen balloon rise in air?
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
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.
How do you make a balloon without a balloon?
There are actually a number of ways to make a balloon lift, without helium. Hydrogen is even less dense than helium (but has the disadvantage of also being highly flammable). And since hot air is less dense than cooler air, you can lift a balloon just by heating air. Since hot air is less expensive than either helium or hydrogen, that is a popular technique.
The evaporative air cooler is an alternative to what other kind of cooler?
The evaporative air cooler is an alternative to conventional central air conditioning. An evaporative air cooling system is more economical to operate than a conventional central air conditioning unit.
