Explain why water boiling in a uncovered pot gets hotter than water boiling in an uncovered pot does.?

Answer 1

The pressure from the steam in a covered pot is greater than if it is uncovered making it able to boil at a higher temp.

Water boils at 100 C and no more than that at normal pressure. If you were to reduce the air pressure (ex. going to a higher altitude) than it would boil at a lower temp. So if you increase the pressure of the air it will boil at a higher temp.

Answer 2

Water boiling in one uncovered pot boils at the same temperature as water boiling in a second nearby uncovered pot. Obviously, one of your "uncovered"s was met to read as covered, but which one? Was your question to have read as this "Explain why water boiling in a covered pot gets hotter than water boiling in a(n) uncovered pot does [sic]? or this "Explain why water boiling in an uncovered pot gets hotter than water boiling in a covered pot does [sic]? Which pot is uncovered in your question makes a big difference.

Here is the correct answer: Water boiling in a covered pot will boil at exactly the same temperature as an uncovered pot boiling nearby UNLESS the covered pot can cause pressure over and above atmospheric pressure on the contents of the pot it is covering. If the covered pot is also pressurized then water will boil in this pot at a higher temperature than the uncovered pot. Only under these conditions will it do so.

The reason is that any liquid boils when its partial pressure is equal to the ambient pressure above the liquid. Water boiling in a pressurized pot will continue to boil at higher and higher temperatures as heat is applied since the ambient pressure continues to increase. Finally, if there is no relief value then there will probably be an explosion as the pressures and temperatures get too high for the vessel containing the boiling water.

Answer 3

When water boils, it remains at 100 degrees celcius. The heat energy supplied to the water is used to break the attactive forces between the water molecules, so that they become vapor. Water inside both a covered and uncovered pot does not become hotter since it's already boiling.

Answer 4

This happens from the material of the different pots. One could be metal and the other is clay, then the metal would attract heat and get hotter than the clay, which does not attract heat.

Answer 5

a covered pot doesn't let the heat and vapor escape, thereby making the inside warmer
