Question

In what kind of pot will a agiven volume of water boil at a higher temperature:a tall and narrow one or short and wide one?

Answer 1

It doesn't matter, water is still going to boil at 212 degrees Fahrenheit. Unless the pot is covered (which could then affect the pressure and therefore, the boiling point), water boils at the same temperature regardless of the pot holding it.

Answer 2

A tall and narrow one will offer a small increase in pressure at the bottom of the pan due to the weight of the water.

If you notice closely, at the start of the boiling, you will see small bubbles begin to rise from the bottom and instead of expanding, they shrink and disappear.

That is due to the temperature gradient in the water, highest at the bottom near the source of heat and lowest near the surface.

Once all the water is heated to boiling, the rapid movement of water all but eliminates the gradient but the temperature required to initiate the boiling will be minimally higher in the taller pot.

Answer 3

a pressurized pot.

Answer 4

Water always boils at 100 degrees C at standard atmospheric pressure, the pot won't matter unless it's enclosed and puts the pressure up then the boiling point goes up.
