Black soot can form on a funnel when there is incomplete combustion of fuel. This happens when the fuel does not have enough oxygen to fully burn, leading to the production of carbon particles. These carbon particles then adhere to the surface of the funnel, resulting in the formation of black soot.
A funnel is traditionally used.
Simply,with dilute Sulphuric Acid and Zinc as essential compounds,You need a woulfs botttle,a funnel and a gas jar as well.First,fill the bottle with zinc chips and fit the funnel.Then connect a pipe from that bottle to a gas jar.Pour the acid through the funnel and the reaction starts.It's an exothermic reaction and releases heat.You'll get the H gas collected in the jar.
differences in the density of solvents allow the separation of two phases..Organic solvents like CH2Cl2, CHCl3 having higher density than water remains at the lower part of separatory funnel which can be easily collected via the stopcock at the end of funnel. *extracting solvent shouldn't be miscible with water, otherwise there will be no separation despite of differences in their densities
To avoid a one too fast colmation of the funnel.
Anything evaporated would be funnelled upwards where the vapour could be collected if a tube was to be fastened to the funnel .

It is a tornado BUT it is funnel shaped NOT an "inverted funnel" The other rotating destructive wind phenomena is not part of a storm (they usually happen on clear, hot days) and is called a whirlwind.

The inverted funnel format is usually used within legal documents. It is also known to be used by doctors but it can be used in any kind of business documents.

Inverted funnel model is a describing models of on-line business or we can define any business through Inverted funnel. Funnel is divided into 3 parts, 1- top of the funnel,2- middle of the funnel and 3- bottom of the funnel. as costumers have tendency to reflect from any single product, they want to test another product so in traditional open funnel model they are less tracked than they could be. so this inverted funnel model comes into picture and we have to encourage people to move vertically upside the funnel by several micro yes with certain level of motivation so we can increase their influence and intensity towards the product by showing them high value proposition and turning then into the loyal customers.

general to specific
Filtrate is collected in a recipient placed under the funnel or filtration apparatus.
It is a glass funnel into which can be placed a circle of folded filter paper (so that it too is the shape of the funnel) liquids may then be poured into the funnel and while the liquids will drain through (to be collected at the base of the funnel), any solids will be retained on the paper.
The funnel increases the area of catchment and makes the reading more accurate by increasing the volume of rain collected. Rainfall statistics must be standardised by specifying the mouth diameter of the funnel if the reading is to have any value.
