How hot does air become when it is heated by lightning?
it get like 9.55 hot
What would happen if cold and warm air mix together and become medium-temperature air?
Since hot air is less dense than cold air, when hot and cold air collide, the hot air is forced to rise over the colder air.
What will hot air do to a barometer?
The air will become lighter causing the barometer to fall. the opposite will occur for cold air.
What 2 things that use hot air to rise?
Hot air balloons and thermal air currents are two things that use hot air to rise. The heating of the air makes it less dense, causing it to become buoyant and lift objects or create upward movement.
Is a hot air balloon filled with nitrogen?
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
When did hot air ballooning become a popular spot in the United States?
1963
What does hot air rises mean?
Hot air rises because it is less dense than cool air. As hot air warms up, its molecules become more energetic and spread out, causing it to rise above cooler, denser air. This movement of hot air is what creates convection currents in the atmosphere.
When hot and cold air meet the hot air rises to the top but which process causes the hot air to rise?
Hot air rises because it is less dense than cold air. As hot air heats up, its molecules become less tightly packed and therefore lighter than the surrounding cold air, causing it to rise. This process is known as convection.
Is a hot air balloon filled with helium?
No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
Why does the beaker become misty?
Beaker is cold and when it meets the hot air it becomes foggy
How is particles used in hot air balloon?
In a hot air balloon, the particles refer to the air molecules inside the balloon that are heated by the burner. When the air molecules are heated, they become less dense and rise, creating lift for the balloon. This process allows the hot air balloon to float in the cooler, denser air around it.
Why is a hot air ballon examples of convection?
A hot air balloon is an example of convection because the process of heating the air inside the balloon causes it to become less dense and rise. This creates a convection current where the hot air rises and the cooler air around it sinks, allowing the balloon to float.
