No, it gets less dense.
As it freezes the hydrogen bonds that make water so cohesive diminish. So as a liquid, water molecules are very close together. When they freeze they are forced into a confirmation where the molecules are further apart. This increases the volume of the same number of molecules, decreasing the density.
You can always remember this fact by remembering that ice floats on top of water.
yes chalk is denser then water.
no
With the exception of water, the particles of an object move closer together and become a solid. Being closer together makes the density rise once it becomes frozen but the density won't rise if the temperature is lowered and the object is already frozen. When water freezes, the density lowers, making ice float.
People can't sink in salt water because if salt is added to water the substance in it will become less denser like the dead sea is so salty that you can easily do yoga or sit and read a book!!!
Using water is an example, anything that is less dense than water will float on water. Anything that is denser than water will sink in water.
from the addition of salt
Yes, water is unique in that it is the only substance that expands when frozen. Therefore ice will be less dense in terms of water molecules than room temperature water or heated water
No. I*f it were, ice would sink in a glass of water. As water freezes, it expands, and becomes less dense.
Particles do make objects denser than they normally may be. For example, if you add particles of salt to water, the water will become more dense. Alternately, if you filter impurities out of water it will become less dense.
Water is frozen to become ice.
When most liquids change to their solid state, they become denser. However, water freezes and the resulting solid, ice, is less dense than it's liquid state (aka ice floats over liquid water)
salt water is denser
if the concentration of salt is increased (more salt added)
less denser than
Liquid water placed in a freezer will become solid ice.
No, frozen water does not become a starch. Starch is a complex carbohydrate found in plants, while frozen water is simply ice in its solid state. Starch is composed of glucose molecules, while frozen water is made up of water molecules arranged in a specific lattice structure.
Water as a vapour (gas?) has to condense back to water, which can then become a solid if frozen.
