No, many do not. The only change they have in common is that they can now flow instead of maintaining a constant shape.
A physical change is a change that can be reversed easily and no new substances are made. Examples are state changes ie. solid to liquid or liquid to gas.
solid/solid liquid/liquid both the same substances together
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
what is mixtures
substances can change to a solid, gas or liquid. solid - precipitate gas - fumes liquid - color change Either way, since its a chemical reaction, there always will be a change in the chemical composistion of a substance.
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
Does it look and behave like water? If not, it is a solid.
1. in most pure substances, melting occurs at a specific Temperature called the melting point. 2. the change of state from liquid to solid is called freezing (solidification) 3. the change from a liquid to gas is called Condensation.
A physical change is a change that can be reversed easily and no new substances are made. Examples are state changes ie. solid to liquid or liquid to gas.
is when the solid is hard then the word is Melting to change to liquid
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
During the melting the structure of the material is destroyed and the liquid is a low oredered state of matter.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
