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.

Will the convection currents stop flowing if the pot is no longer heated?

What is liquid holdup in a column?
'Liquid Hold-up' in a distillation column refers to down-coming liquid (liquid traffic travelling down the column) becoming trapped in the column's packing material. Packing material is used in distillation columns to increase the contact efficiency between the down-coming liquid stream(s) and the up-flowing vapour stream(s). The packing materials do this by increasing the surface-to-volume ratio over which the vapour and liquid streams come into contact in order to promote separation between the more volatile and less volatile components in the column. The down-coming liquid can become trapped in the packing material for a number of reasons. One example is when liquid becomes trapped in crack formations or fractures of the packing material (which can occur during normal or non-steady state column operation). When the liquid becomes trapped in these cracks/crevices, contact with the up-flowing vapour stream becomes non-existent and the liquid is literally 'held up' from travelling down the column.
Can you add cold liquid to corningware while it is in the oven?
It is not recommended to add cold liquid to Corningware while it is in the oven as sudden temperature changes can cause the dish to crack or shatter. It is best to let the dish cool down slightly before adding cold liquid.

Does lungs absorb food and liquid that goes down into lungs?
No. Food and liquids should not go down into the lungs. That is why one coughs excessively when food or liquid "goes down the wrong tube." Aspiration is the term for breathing food or liquid into the lungs, and frequently causes a severe pneumonitis and may result in pneumonia.
When you melt chocolate you are changing a solid in to a gas or liquid?
When you melt chocolate, you are changing a solid into a liquid. The heat causes the chocolate to break down its crystalline structure and become a smooth, flowing liquid. It does not change into a gas unless heated to a much higher temperature for a prolonged period.
Why do you think sudden coughing while drinking is a useful reflex action to a person?
If the liquid goes down the wind pipe, coughing will prevent it from going into the lungs where it can make you sick.
What is an example of flowing freshwater?
A mountain stream, or a river flowing lower down in the valley.
