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 are two kind of changes in matter?
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
What is heterogeneous physical?
Heterogeneous physical refers to a system where the components or substances within it are not uniform or of the same kind. This means that there are different types of materials or substances present within the system, displaying varying physical properties or characteristics.
When matter changes state does become a different kind of substance?
Changes of state of matter are physical processes, the molecule remain unchanged.
Can you reverse physical changes?
Physical changes, those changes that do not involve chemical changes or nuclear changes, can be reversed, though doing so may be difficult in some cases. To cite a single example, water can be frozen and then thawed. Or it can be boiled off and then condensed.
Difference between chemical and physical changes?
a physical change is the form of matter but not in its chemical identity or is when the state or shape of matter is changed.physical change is reversable or temporary while a chemical is permenent or cannot be reversed.a chemical change is a change in which one or more kinds of matter are transformed into a new kind of matter.

What kind of changes in substance are always physical changes?
each substance has a density that differ from the densities of other substance.

Is a match ignites to form ash and mixture of gases a physical or chemical changes?
The process of a match igniting to form ash and a mixture of gases involves a chemical change. This is because there is a chemical reaction taking place when the match combusts, converting the matchstick's materials into new substances like ash and gases.
What kind of variable is always changing?
the y variable always changes and x is constant
Can chemical reactions have physical changes?
No, chemical reactions involve changes in the chemical composition of substances, while physical changes involve changes in the physical state or appearance of a substance without altering its chemical composition.
A kind of change in matter that produces a new substance?
Nuclear and Chemical changes result in new substances.

What type of Materials that can be change?
Various materials can undergo change, such as solids, liquids, and gases. These changes can include physical changes like melting or boiling, and chemical changes that result in new substances being formed. Materials like metals, plastics, and organic compounds can exhibit different transformations under specific conditions.
In terms of chemical bond and electrons what kind of changes occur between atoms when substances undergo chemical reaction?
