Yes
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.
It takes longer to boil because there is more of it that therefor takes longer to heat up. This is because a larger volume of liquid is needed to be heated to the same temperature as a small volume of liquid.
To heat anything up, you need 'energy.' One kilocalorie of energy is sufficient to raise the temperature of one gram of water by one degree Celsius. So you would require more energy to heat up larger amounts of water. Considering your stove consistently gives off the same amount of energy,(heat) it will take longer for your stove to give off the necessary energy.
50ml of water will boil faster than 100ml of water since there is less water to heat up. The larger the volume of water, the longer it will take to reach boiling point.
Water with salt will actually take longer than water without salt to evaporate. This is due to boiling point elevation. If you put a solute into water, it will make it more difficult to boil, and therefore will boil at a higher temperature. Since it takes longer for the salt water to boil, it will take longer for it to evaporate as well
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
Water takes longer to boil at higher elevations because the atmospheric pressure is lower, which reduces the boiling point of the water. At higher elevations, there is less air pressing down on the water, so it needs to reach a higher temperature to boil.
The boiling point is increased after adding impurities to water.
No. A large mass of water will have the same boiling point as a smaller mass of water. Differences in pressure, however, will cause differences in boiling point. - - - - - It takes longer to boil a large amount of water than a small amount because it takes longer to heat it up.
Hot water takes longer to boil than cold water because hot water is already closer to its boiling point, so it requires more energy to reach the boiling point compared to cold water.
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
