## Does a kettle boil quicker with less water?

Its all due to surface area to volume ratio. When it is high all the molecules of water acquire higher energy is faster to boil whereas when the ratio is low it takes a lot of time for the molecules to acquire their minimum energy to get boiled.

## Why do large volumes of water take longer to heat?

Compared to air or land, water is a slow conductor of heat. That means it needs to gain more energy than a comparable amount of air or land to increase its temperature. … That means that, once heated, a body of water will hold onto that heat for a much longer period of time than either air or land.

## Why does it take longer to boil a kettle of water than to warm the same kettle of water to a lower temperature?

The rate of heating of a liquid depends on the magnitude of the temperature difference between the liquid and its surroundings (the flame on the stove, for instance). … Because it takes cold water some time to reach the temperature of hot water, cold water clearly takes longer to boil than hot water does.
