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).

Does it take more heat to heat water or to boil water?
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
What will happen when atom and molecules of substance melt freeze boil or condense?
When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.
How does adding or removing heat to a system result in of temperature or change in state?
then the temperature either goes up or down. When you add heat to a substance the substance normally spreads out more for on a subatomic level the atoms vibrate more. Gases have a larger volume at the same pressure and fluids can increase in volume too. Solids normally expand. The opposite to the above is true with a decrease in temperature. It is good to note that if you melt ice it decreases in volume which is proof that heat dose not always expand the substance.
Does the melting point of aluminum change with the thickness?
The melting point of any given substance (such as aluminum) has nothing to do with the thickness or shape of the material being melted. It will melt at the same temperature. But it does require more heat in order to heat a thicker piece of aluminum to its melting point.
Do salt water boil faster than non salt water?
Adding a salt to a substance changes its boiling and freezing points, but it lowers its freezing point and raises its boiling point. So, salt water actually takes more heat to boil because the salt has raised the boiling point.
Why does a substance take longer to boil than melt?
because substances boil at a higher temperature than when it melts. therefore, boiling takes more energy than melting and more energy takes more time.
Does it take more heat to heat water or to boil water?
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
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.
What will happen when atom and molecules of substance melt freeze boil or condense?
When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.
How causes steel to melt ice?
There is no inherent property of steel that causes it to melt ice. Ice will melt if it comes in contact with something that is warm enough to melt it, regardless of what it is made of. One possible advantage that steel has is that, like any metal, it is a good conductor of heat. This would allow it to transfer heat more quickly than a nonmetallic substance.
How could a liquids boiling point be used to determine if it is a mixture or a pare substance?
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
What is the relationship between specific heat and the change in temperature of a substance?
Specific heat is the amount of energy it takes to raise a unit mass of the substance by one degree Celsius. For each unit of specific heat applied to a substance its temperature will increase by a set amount.
How would a microwave oven heat ice versus liquid water?
The actual process of heating would be exactly the same. Microwave energy would begin to excite molecules of water, making them move more quickly and heating them up. Eventually the ice would melt, then boil. The water would heat up then boil.
Why does having more surface melt ice the fastest?
It is because when surface is more, more does the ice get exposed to heat and thus quickly attains heat and energy. This makes it melt faster.
Heat never of itself flows from a cold to a hot substance?
Heat can flow from cold to hot substances. It's flow depends on the total amount of heat of the substance not on the temperature. It flows from the substance which has more heat to the substance which has less heat stored in it.
How does adding or removing heat to a system result in of temperature or change in state?
then the temperature either goes up or down. When you add heat to a substance the substance normally spreads out more for on a subatomic level the atoms vibrate more. Gases have a larger volume at the same pressure and fluids can increase in volume too. Solids normally expand. The opposite to the above is true with a decrease in temperature. It is good to note that if you melt ice it decreases in volume which is proof that heat dose not always expand the substance.
Is the melting point of a substance is the same as it's surroundings?
no this would depend on the atoms of the substance. for example if you have a block of ice and a block of butterthe block of ice would melt faster because its atoms move more faster to heat than butter does
