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

Why does it take the water longer to boil when it has salt in it?
impurities rise the boiling point
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 much salt do you put in to make the water boil faster?
Adding salt to water will make it take longer for the water to boil. You should wait until the water is already boiling to add salt.
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 sugar water longer to boil than plain water?
When a solute is added to a solvent, such as water, it increases the boiling point. Instead of boiling at 100 degrees Celsius (for water), it will boil at a higher temperature. This phenomenon is called boiling point elevation.
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 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.
Why does it take the water longer to boil when it has salt in it?
impurities rise the boiling point
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 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.
Why does it take longer to boil more liquid instead of less?
Because theres more liquid.
Why does salt water take longer to boil?
The boiling point is increased after adding impurities to water.
Thickness of liquid affect it's boiling rate?
the thicker a liquid is the longer it take to boil!
Does looking at water make it take longer to boil?
No, it only makes it feel longer because you are more aware of the time being taken.
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
Why does it take longer for a larger quantity of ice to melt then it does for a smaller quantity?
Because there is more ice.
