Water atoms do not expand or multiply when heated. When water is heated, the heat energy causes the water molecules to move faster and farther apart, which results in the expansion of the water volume. The number of water molecules remains the same.

How does something expand?

Most things will usually expand because the atoms in it get heated and force the boundaries outward. Water is the exception which expands when frozen.

Do all objects expand when heated?

No, not all objects expand when heated. Most objects do expand when heated, but there are exceptions such as water between 0°C and 4°C, which contracts when heated. The expansion or contraction of an object when heated depends on its material properties.


Do most solids expand when cooled?

No, most solids contract when cooled, as the lower temperature causes the atoms or molecules to move less, leading to a decrease in volume. However, there are exceptions, such as water, which expands when cooled below 4°C before turning into ice.


What liquid expands when heated?

All liquids expand when heated. e.g. Mercury in a thermometer. One exception may be water when heated form 0 to 4 degrees Celsius.


Solid liquid or gas expand the most when heated?

Gases expand the most when heated compared to solids and liquids. This is because the particles in a gas have more kinetic energy and move more freely than particles in a solid or liquid, allowing for greater expansion when heated.

Does water expand when heated and why?

Yes... When water is heated, the intermolecular force of attraction between water atoms become weak and they start losing the intermolecular force of attraction... at temperature known as boiling point of water this intermolecular force become so weak that water lose its state and converts into gasious state... but this expansion is not considerable... :)


Why do cereal grains expand upon cooking?

the process is called gelatinization- which occurs when heated starch molecules absorb water and expand. sometimes they expand 2-3 times their volume when cooked.


Is hot water denser than cold water?

NO, it is the opposite. remember molecules expand when heated


What happened when water heated?

when water gets heated it starts to get excited and it stats to boil and there are atoms inside which viabrate and makes the water boil.
