When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
What else can I help you with?
Are physical changes chemical reactions?
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
How do chemicals relate to physical science?
Chemicals can relate to physical science because we use different gases that need chemicals in them
What kind of changes in substances are always physical changes?
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.
Are chemicals from plants physical or chemical weathering?
Is chemicals from plants chemical weathering or physical weathering
Can nylon change?
Nylon itself does not change chemically, but it can undergo physical changes such as stretching, shrinking, or fading with exposure to heat, light, or chemicals. These changes can affect the appearance and properties of the nylon material.
Why do physical properties change when chemicals combine?
Physical properties change when chemicals combine because when you mix chemicals the physical properties changes it identity.
Is etching glass with acid a chemical or physical change?
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
What kind of changes in substance are always physical changes?
each substance has a density that differ from the densities of other substance.
Are physical changes chemical reactions?
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
How are physical properties differ from physical changes?
Physical properties describe characteristics of a substance that do not involve a change in its chemical composition, such as color or density. Physical changes, on the other hand, refer to alterations in the substance's physical state, like melting or boiling.
How do chemicals relate to physical science?
Chemicals can relate to physical science because we use different gases that need chemicals in them
What kind of changes in substances are always physical changes?
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.
Are chemicals from plants physical or chemical weathering?
Is chemicals from plants chemical weathering or physical weathering

Are state changes chemical or physical changes?
Physical Changes
The physical properties of a solution that differ from those of its solute and solvent include freezing point boiling point and what?
The physical properties of a solution that differ from those of its solute and solvent include boiling point elevation, freezing point depression, osmotic pressure, and vapor pressure changes.
Is chemicals from plants chemical and physical weathering?
Chemicals from plants can contribute to chemical weathering through processes like root exudation, where plant roots release substances that can break down minerals in rocks. Physical weathering, however, involves the mechanical breakdown of rocks without changes in chemical composition and is more likely due to factors like temperature changes and weathering.
