When a substance freezes it enlarges.
Density increases when a substance contracts as it freezes. The substance will have the same mass but with a smaller volume.
Correct, the temperature at which a substance freezes is lower than the melting point.
Its density goes down because when water freezes it expands.
It is dispersed into the environment
The arrangement changes because the freezing point. When something freezes it changes into a new substance and that is arranging it into a chemical change.
As a substance freezes, its particles attract each other and pull in towards each other. Their mobility slowly declines as the solid forms.
Type your answer here..the shape and volume
Yes. Usually when a substance freezes, or becomes a solid, it will decrease in volume, causing an increase in density. Water is an exception, which is less dense when it freezes/becomes solid.
A substance loses energy both when it freezes and when it heats up.
The particles get attracted to each other, forming a solid.
Unlike any other substance, it expands when it freezes.
The Point The Substance Freezes Or Melts
It goes to the environment.
Yes it does affect, the denser the substance is, the lesser the temperature needed for it to be frozen . Hence . Density of a substance is indirectly propotional to the temperature it needs to be frozen.
There is less of it and the rest gets trapped inside.
A suitable mixture of salt water.
When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
The rate at which the substance melts determine the rate at which it freezes. other condition remain the same
The answer is that the temperature a substance freezes is also its melting point. Water freezes at 0 degrees Celsius into ice and if you heat ice up to 0 degrees Celsius it MELTS to give you water. Evaporation is the change from liquid to gas and condensation is the change from gas to liquid (for water this happens at 100 degrees Celsius).
Freezing is exothermic as a substance loses heat to its surroundings when it freezes.
the particles get attracted to each other and form a solid.
A type of change like melting is a physical change of a substance. There is no chemical change when a substance melts, freezes, or evaporates.
is a characteristic of a pure substance that can be observed with out changing it into another substance ex:a physical property of water is that it freezes at a temperature of 0degress C when liquid water freezes it changes to solid ice but it is still water
Yes. A substance melts and freezes at the same temperature. Melting is as it changes from solid to liquid, freezing is from liquid to solid.
