What else can I help you with?
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.
What is the difference between an updraft and a downdraft?
Updrafts are systems of hot air, which rise. Birds and expert hot-air ballooners use them. Downdrafts are systems of cold air that tend to fall and bring things flying in it with them.
How do you prove that hot air rises?
Hot air is less dense (lighter) than colder air, so warmer air will naturally rise above the cooler air.
What should a hot air balloonist do to go higher?
They can drop weight over the side, increase the hot air volume, or both. A hot air balloon will rise when its buoyancy exceeds its weight. So the balloonist can increase the buoyancy by increasing the amount of hot air contained in the balloon. Or they can simply reduce the weight of the balloon, including the gondola, its contents, and contained hot air.
Does hot water rise and cold water sink?
HOT rises COLD sinks
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.
Will a balloon rise higher with hot air or cold air?
Hot air
Why would heating the gas in balloon make the balloon rise?
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
Does heat rise or hot air rise?
Hot air rises. As air is heated, it becomes less dense and therefore more buoyant, causing it to rise. This is due to a difference in temperature creating a temperature gradient, leading to the movement of air.
What does hot air rise due to?
i
Does hot and cold air fall or rise?
Hot air rises and cold air falls.
When hot and cold air meet the hot air rises to the top. Which process causes the hot air to rise?
Convection
How does hot air rise?
Hot air rises because it is less dense than cold air.
Why does cold or hot air rise?
Cold air is denser than hot air, so it is heavier and sinks while hot air is lighter and rises. This movement is known as convection, where the warmer air displaces the cooler air, causing it to rise.
What kind gas is used in hot air balloon?
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
Does hot air expand and rise?
yes
What does air do at the equator?
Mostly get hot and rise.
