Does a kettle boil quicker with less water?
Originally Answered: Why does less water boil faster than more 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.
