If water is boiled in a flask with a closed lid which part of the flask will you look for the condensed water?
Answers
Answer: 5
You can understand this well by thinking about why a liquid boils in the first place. Imagine you have a pot of water, and it's just sitting there in your kitchen. Intermolecular forces (specifically hydrogen bonding for H20 molecules) keep the water in liquid state. The air molecules zipping around the pot and above the water's surface represent a certain pressure. Let's say your kitchen has standard conditions, so 1 atm. Then, you put the pot on a stove, and heat the water up. This heat breaks the intermolecular bonds between the liquid molecules. Now, the only reason the molecules rise up and become water vapor is because the kinetic energy of the water molecules matches that of the surrounding air. Pressure moves from high to low, and as the water boils, certain molecules acquire the necessary speed (and therefore pressure) to enter the gaseous state. Keep in mind that heating the pot negligibly changed the kitchen pressure. The pressure in your kitchen should still be about 1 atm, since the vast air space should distribute the heat produced by the stove.

Explanation:
The boiling point might rise a little over the normal boiling point because the pressure in the house will increase a little bit as you boil off the water. If the container is closed, all vapor generated by boiling will stay in the container. If it is at constant volume, the pressure will rise in it.
