expand
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.
Generally speaking, substances have the least amount of surface area as a solid, as they are heated they form a liquid and expand, as this is heated it forms a gas and expands more. *Assuming pressure is constant **Water is the only substance to expand as it freezes
All liquids expand when heated. e.g. Mercury in a thermometer. One exception may be water when heated form 0 to 4 degrees Celsius.
same number of atoms theoretically... yet cold objects collect water vapor cold objects shrink and hot objects expand with the exception of water.
Most materials expand when heated. A few contract under certain circumstances, for instance water contracts when heated between 1 and 4 degrees C. Some change colour, e.g. zinc oxide. Whether they could double in size depends on the material and the temperature increase.
Because it is in contact with something colder. When a warmer body is in contact with a cold body, the warmer one will give off heat to the cold one. This cools the warmer one and warms the cooler one.
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.
Yes. Water is one of the few substances on earth that does expand when frozen most other things expand when heated. The hydrogen bonds between the hydrogen and oxygen atoms straighten and the water molecule expands.

Ice (frozen water) and Water (below 4 oC) expand when cooling. This is exceptional! Other substances, also Water (above 4 oC) expand when heated.
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... :)
What size cistern what temp
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.
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.
NO, it is the opposite. remember molecules expand when heated

Heat = expansion. The water molecules expand when heated. The container will expand, and then the measurment will be off?
