Substance
Homogeneous matter has the same composition and properties throughout, like air or sugar water. Heterogeneous matter has varying compositions and properties within the sample, like a fruit salad or a mixture of oil and water.
The chemical composition or properties of the substance remain constant regardless of the quantity present.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
Physical properties are characteristics that can be observed or measured without changing the composition of the substance. When physical properties are altered, such as when a substance changes state (solid to liquid), the basic chemical composition remains the same, indicating that it is still the same kind of matter.
That is a physical change. The chemical composition of the substance does not change during a physical change, only its physical properties like size, shape, or state of matter.
These substances are called isotropic.
A uniform mixture is : A sample of matter that has the same composition and properties throughout.
term for that is pure substance
A sample of matter is considered homogeneous if its composition and properties are uniform throughout. This means that the sample has the same characteristics, such as color, density, and chemical composition, in all its parts. This uniformity allows for consistent behavior and properties within the sample.
Homogeneous matter has the same composition and properties throughout, like air or sugar water. Heterogeneous matter has varying compositions and properties within the sample, like a fruit salad or a mixture of oil and water.
The chemical composition of the matter will stay the same during a physical change. Only the physical properties, such as shape, size, or phase, will be altered without affecting the chemical composition of the substance.
The chemical composition or properties of the substance remain constant regardless of the quantity present.
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
A change in some properties of matter without forming a different kind of matter is called a physical change. This can involve changes in state, shape, size, or appearance of the substance, but the chemical composition remains the same.

no you cannot find matter in nonliving things and it does not have the same properties
