Do most solids expand when cooled?
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
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.
How many atoms are needed to make 30000000000000000000 molecules of water?
There are 3 atoms in one molecule of water (H2O is two hydrogen atoms and one oxygen atom)... so just multiply the number of molecules by 3.
Does a cold object have more or less atoms?
same number of atoms theoretically... yet cold objects collect water vapor cold objects shrink and hot objects expand with the exception of water.
What happens to material when heated do they expand contract change color double the size?
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.
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.
Does water freeze when it expands?
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.

What percentage does water expand when heated?
0%
Solid liquid or gas expand the most when heated?
Ice (frozen water) and Water (below 4 oC) expand when cooling. This is exceptional! Other substances, also Water (above 4 oC) expand 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... :)
How much will water expand in a cistern when heated?
What size cistern what temp
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.
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.
Is hot water denser than cold water?
NO, it is the opposite. remember molecules expand when heated
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.
Why not measure amounts of liquid when hot?
Heat = expansion. The water molecules expand when heated. The container will expand, and then the measurment will be off?
