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.
Why is air cooler in the mountains than the plains?
Cause its higher
When a sound from a source is refracted away from the surface of the earth it gives an indication that the air is cooler than the ground?
Ground is cooling faster than the air.
Does air have more or less pressure than still air?
Yes, it has more pressure than still air because it has a greater force.
Insulating properties of cotton?
Dry cotton holds air still. Dead air space (not moving) is the best natural insulator.
Does still air move?
Yes. Sill air is defined as air that moves less than 25 from.
Does moving air has lesser molecules than instill air?
Moving air probably has less molecules than still air because the particles are spread apart in moving air, and there is less of them, while in nonmoving air, it is packed.
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.
What makes hot air turn to cold air?
Heat is defined by how fast molecules are moving. Fast moving molecules will have a higher temperature than slow moving molecules. The kinetic energy of the hot air is transferred to the cold air, which means the cold air becomes a little warmer, and the hot air becomes cooler.
Air moving from land to water?
At night, land cools much more rapitly than ocean water. Air over the land becomes cooler than air over the ocean. Cooler, denser air above the land moves over the water, as the water rises. Movement if the air toward the water from the land is called land breeze.
What causes the temperature gauge to go down while driving?
If the temp sensor is measuring outside air, It could be exposed to the air moving over the vehicle which moving air feels cooler than still air, If any one lives in Orlando, FL can tell you. hello.there. there is no way that the temp sensor could read the outside air. your temp sensor goes down when you drive because air is streaming through your cars grille a lot faster than when you are sitting still or parked. that is the way they are design to work and this is a fact.
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.
Is Hydrogen cooler than Air?
Hydrogen is lighter than air. As to the temperature it depends on where the heat source is, hydrogen can either be warmer, cooler or the same temperature as air
Why is it cooler at the beach during the day?
Usually a beach has a breeze blowing in from the ocean. This movement of air can cool your skin and make the temperature seem less. I would think that the air is still in the morning and as the sun heats up the air and land, this results in movement of the air.
Why do hot air raise?
Because it is lighter than cooler 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.
