Why do people boil cold water not hot water?
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.
Does hot or cold water make a difference?
When you heat up water, the water molecules start moving around faster and faster.Because there’s more space between the molecules, a volume of hot water has fewer molecules in it and weighs a little bit less than the same volume of cold water. So hot water is less dense than cold water.

Will adding salt to water make it boil faster?
When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said.”The temperature of saltwater will get hotter faster than that of pure water,” Giddings said.
