Heat.
The condenser acts through cooling with a greater surface area (on the inside of the condenser); the constant fluid flow keeps the temperature down. If you were to assemble the apparatus so that the water flows from top to bottom, the condenser would never fill up, and your reaction will have difficulty cooling down.
Risky if you have volatile chemicals or a reaction that you need to keep cool.
Liebig condenser is used to cool down evaporated products into liquid. It becomes less effective when direction of?æ water flow is reversed.

Upper portion is heated as it acts as a control for comparing with lower portion of the test tube.Turbidity occurs in the upper portion of urine,while lower portion remains clear.Turbidity may appear due to phosphates,carbonates which on addition of acetic acid if persists denotes presence of proteins in the urine.
For a gas or vapor to be flammable or an explosion hazard it must have a concentration in air between the Lower Explosive Limit (LEL) and the Upper Explosive Limit (UEL) for that particular gas or vapor.

opposite upper is lower Normandy.What do upper and lower refer to?
He lived some where in lower Egypt. But lower Egypt is upper Egypt because upper is lower and lower is upper.
The crowns of upper and lower Egypt were combined because King Menes combinded upper and lower Egypt. He decidd to combine upper and lower Egypt and the crowns.
Upper Egypt and Lower Egypt
Because if water enters from the lowest point, the condenser will always be filled with cold water to ensure efficient cooling. The water should always flow into a condenser at its lowest point and exit from its highest point. This avoids trapping air in the water jacket.
you do work out the upper and lower quartile
