I have a problem in physics. We are doing heat and temperature. We put water in a conical flask and put a capillary tube and there are no space for air to travel. We record the volume of the water which is in the capillary tube. Then it is heated. How does the water falls and then rises. Please answer me it is base on 40 percent of my marks.

condensation and evaporation

The reason is because the conical flask that is made of glass expands first upon heating, then only the water.
That is why when the glass expands, you see the water level drops, but water level rises after that, just because the water then starts to expand.

The water gets to a undeniable temperature, after boiling factor, the place it evaporates, and is going into the air as steam. The evaporated water then cools down and condenses, we call this condesation because it returns to water returned.

At a guess, when it is first heated and the molucules begint o become excited, air and other gases escape so it becomes heavier.
Tehn as it is heated, it begins to change to steam and the molecules separate and it becomes lighter as it becomes a gas and rises.

Water falls because of gravity.
Water rises because of evaporation.

Magic.
If you don't believe me, then perhaps you should study.
