It takes less time to boil little amounts of water because there is less water to boil. The more water in the pot, the longer it takes to heat up.
because it takes less time for the water to boil. I f you put more water in the kettle it will take a longer time for it to boil which takes in more energy
If there is a drought or normally low ammounts of water available it can become expensive and if we use all of the water out of rivers, could destroy native habitats/ecosystems.
A small amount of water will reach it's boiling point sooner than a large amount of water. It will not boil faster.
On top of a mountain
less than 100oC.
When you boil water, the water near the stove burner becomes less dense. This is because the water molecules absorb heat and become energized, causing them to move more rapidly and spread out, resulting in lower density near the heat source.
When the gas phase pressure is less than 1 atmosphere.
Because the boiling point of ethanol (the alcohol in vodka) is lower than that of water.
no because at the top of the mountain its less pressure than at the sea level so it will take more time to boil
That is not possible a full kettle has more water,therefore it will take longer to boil.
on a normal pressure (1 atm) water boils on a temperature of 100 C, but when we reduce the pressure, ebullition temperature will be also reduced (it will become less then 100) which means that they can boil more water using less energy
It depends on the battery and the size of the kettle. It also depends on the starting temperature of the water and the air pressure, if you are at higher altitude or lower air pressure it takes less energy to boil the water, and also if the water starts at a higher temperature it takes less energy to boil. Definitely some batteries have enough energy. You'd have to calculate the amount of energy required to boil the water and look at the amp hour measurement on the battery, that tells you the total energy stored in the battery.
