because substances boil at a higher temperature than when it melts. therefore, boiling takes more energy than melting and more energy takes more time.

How much salt do you put in to make the water boil faster?

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.


Why would water take longer to boil at elevations above sea level?

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.


Why does the amount of water affect time it takes to boil?

The basic formula which describes the energy required to raise the temperature of a substance is ΔE=mcΔθ. where: ΔE = Difference in energy m = mass of the substance c = specific heat capacity of the substance Δθ = change in thermodynamic temperature without any calculation, it is clear that if the change in temperature is the same (i.e. from room temperature to boiling point); and the specific heat capacity is the same; the more of the substance that is being boiled; the more energy is required. If the device which is boiling the substance is at a constant power, whether it be a burner or a kettle, the more energy required to boil the substance, the more time it will take to boil so long as the power is held constant.


Why does it take longer for water to boil when there's more of it?

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.


How long does it take for water to boil in a foam cup?

It typically takes about 5-10 minutes for water to boil in a foam cup. However, caution should be exercised when boiling water in a foam cup as it can potentially melt or catch fire due to the heat. It is not recommended to boil water in a foam cup for safety reasons.

Why does it take more heat to boil a substance than to melt it?

The energy required to completely separate the molecules in a liquid and convert them to a gas (boiling), is greater than the energy needed to completely separate the molecules in a solid and convert them to a liquid (melting).


Do larger amounts of water take longer to boil?

Yes


Why would it take longer to boil an egg above sea level?

It takes longer to boil an egg above sea level because the atmospheric pressure decreases at higher altitudes, leading to lower boiling points. This means that the water will boil at a lower temperature, causing it to take longer to cook the egg.


Why does half a full kettle take less time to boil a full one?

That is not possible a full kettle has more water,therefore it will take longer to boil.


Does it take longer to melt chocolate with more sugar or less sugar?

Choclate with less sugar is easy to melt and the more sugar you have the harder it is to melt.


Why does salt water take longer to boil?

The boiling point is increased after adding impurities to water.


Why does it take longer to boil more liquid instead of less?

Because theres more liquid.


Will water with salt evaporate faster than water without salt experiment?

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

Will a little pot or big pot boil first?

The deeper the water the longer it will take to boil. So if you put a small amount in a big pan it will boil much faster than a small amount in a small pan.


Why does it take a less time to boil little ammounts of water?

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.


Does soup with vegetables take longer to boil than clear broth?

Yes, given that the vegetables have more mass than just plain broth. The denser the objects, the longer it will take to heat.
