Why does gravity not pull smoke down?

Here is his response: Fires on earth are anchored by gravity, but the combustion gases are hot and light, so they rise. In space, where we have little or no gravity, there is nothing to make fires go up, and the fire has a harder time obtaining a supply of oxygen.

Why is air not affected by gravity?

The answer is: gravity. Air *has* “fallen to the ground due to gravity” – with the force of 14.7 psi at sea level. At higher elevations, there is some air beneath one’s altitude, so there is less air above pushing down (from gravity), and, therefore, the atmospheric pressure is less at higher altitude.

Does gravity pull down air?

As gravity hugs the blanket of air to the Earth’s surface, what physicists call a density gradient is set up in the air. The air near the ground is pulled on by gravity and compressed by the air higher in the sky. This causes the air near the ground to be denser and at a greater pressure than air at higher elevations.

Is Steam affected by gravity?

The Gravity Cycle During a Gravity Cycle, steam is pumped into a chamber containing ambient air. Because steam has a lower density than air, it rises to the top of the chamber and eventually displaces all the air.

Why does smoke rise against gravity?

Smoke rises for the same reason ‘hot air’ rises, convection currents. “Smoke”, strictly speaking, consists of particles of ash carried on the hot are from burning. Since hot air is less dense than cold air, it rises as it is displaced by the heavier cold air.

Does gravity pull gas?

Yes gravity pulls on gas molecules. That is why the atmosphere doesn’t just float off into space. The gist is that the time between collisions is very short in the lower atmosphere, and the distances very short.

Why do all objects fall but smoke rises?

Convection is the transfer of heat by the physical movement of hot masses of air. As air is heated, it expands (as do all objects). As it expands, it becomes lighter then the surrounding air and it rises. Soon a convection column is formed above the fire which can be seen by the smoke that is carried aloft in it.

Why does hot steam rise?

When water is heated it evaporates, which means it turns into water vapor and expands. At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created. The opposite of evaporation is condensation, which is when water vapor condenses back into tiny droplets of water.

Are gases pulled by gravity?

Yes gravity pulls on gas molecules. That is why the atmosphere doesn’t just float off into space. The gist is that the time between collisions is very short in the lower atmosphere, and the distances very short. The mean free path at atmospheric pressure is only about 70 nanometers.
