What sphere acts as a lid preventing air flow rising upward?

The tropopause acts as a lid preventing air flow from rising upward. It is the boundary between the troposphere and the stratosphere and plays a crucial role in controlling vertical air movements in the atmosphere.

What is flooding point?

In a packed or tray column where you have vapor flowing up and liquid flowing down, there is an upper limit to how fast the liquid can drain downwards. The point at which liquid cannot flow down as fast as it is coming into the column is the "flooding point". The actual flooding point is partly dependent on how fast the liquid can flow down with no vapor flowing upwards and the rate at which vapor is trying to flow upwards. Cross sections of the column occupied by vapor are not available for liquid flow - effectively reducing the cross-section for downward flow of the liquid. You also get entrainment of liquid in the upward flowing vapor and drag on the liquid as it fights the direction of the vapor flow - the vapor wants to go up while the liquid wants to go down. This additional drag also slows down the flow of liquid trying to drain downward in the column. There is an analogous condition for two-phase liquid/liquid extraction columns.


What are convection waves?

Convection waves are a churning upward motion from the up welling of warm liquid or gas, and the concurrent downward flow of cooler material to take its place.


Why does water in a siphon flows upward against gravity?

Water in a siphon flows upward against gravity due to atmospheric pressure pushing the liquid up the shorter arm of the siphon tube. The weight of the water in the longer arm creates a pressure difference that drives the flow to overcome gravity and flow up the tube.


Why is a liquid able flow?

a liquid is able to flow because its freely moving particles allow liquid to flow from place to place

What is the liquid property that allows oil to flow upward in the wick of a lantern?

Liquids are able to travel up narrow tubes or threads because of capillary action. This property causes part of the surface of a liquid to elevate above the rest of the surface when in contact with a solid.
