What would happen if there was a lid on a pot of boiling water?

The heat would stay in the pot and if you don't watch the boiling water it could over-boil. Other than that, nothing would really happen.

Is the boiling temperature higher or lower when you use a lid?
If the lid is tight enough to raise the pressure in the pan (as in a pressure cooker), the boiling temperature will be higher. However, if the lid just sits loosely on top, it will make the water boil sooner because not as much heat is lost and the water heats up faster.
Does boiling water evaporate faster with or without lid?
Water will evaporate faster with alid on the pan, this is simple rule of kinetic energy
What happen when a pencil lid go inside your body?
Nothing
Why does steam in boiling kettle raises the lid?
It is like a planes wing, it causes the molecules on the top of the lid to want to "run" away from the burning steam, so they move vertically away. Some of those molecules will have some sort of slight attractive force with the lid, wether it be magnetic or so on, and if enough of them have enough attraction to the lid, then it will lift up
Why dows running hot water over a tight lid make a jar easier to open?
The heat causes a slight expansion of the lid, which relieves pressure of the lid against the jar.
Why do water droplets form on a lid when boiling water?
The lid is cooler than the steam (water vapor) produced by boiling the water. When the water vapor contacts that cooler surface, it condenses into liquid water.
What is happening when boiling vegetables on a stove and the lid pops up?
air is escaping. boiling veg in water causes air bubbles to be formed, which pressurize the lid up. Jimmy Neutron

What would happen if you poured boiling water into a jar?
Glass is a great conductor of heat but it doesn't hold it long. If you were to stick 212o (Fahrenheit) water into a glass jar it would begin bringing the glass jar to the same temperature as the water on the inside very quickly (equilibrium). It also begins building pressure, so If a lid is on the jar it could potentially explode the jar sending boiling liquid and glass shards everywhere.
What would happen if you put 8 ounces of water into an eight-ounce glass cup with a sealed glass lid and started boiling the water?
As some of the water passed its temperature of vaporization and turned to steam, steam pressure inside the cup would steadily increase, and would eventually exceed the structural integrity of the cup, whereupon the experiment would suddenly and catastrophically metamorphose into a dangerous mess.

Why does the lid fly off a boiling container?
The lid will come off because as the water heats up it expands and turns to steam. This pushes the air inside upwards so forcing the lid to rise.
What action will most likely occur after placing a lid on a very full pot of boiling water?
the pressure inside the pot will build up and pop the lid off
What will happen if you put a glass bottle containing teaspoonful of water in it in the sun with its lid closed?
Not much will happen if you put a glass bottle containing teaspoonful of water in it in the sun with its lid closed. It might evaporate.
What do you need for canning and perserving?
Glass container with lid like peanut butter jar and boiling hot water
How do you reduce evaporation rate in boiling water?
Fit a lid or reduce the heat Evaporation rate will actually increase if you boil water at increased pressure as the vapour pressure, to achieve boiling, must increase to that pressure.
If a metal can is heated with the lid open and then the lid is replaced and the can is allowed to cool what would happen to the can and why?
If the lid formed a seal, it should sag from the outside pressure.
