Are Name two categories used to classify properties matter?
Two categories used to classify properties of matter are physical properties and chemical properties. Physical properties can be observed or measured without changing the composition of the substance, while chemical properties describe how a substance changes into a new substance through a chemical reaction.
What are two physical properties that don't depend on size?
Density and melting point are two physical properties that do not depend on the size of a material. Density is the mass of a substance per unit volume, while the melting point is the temperature at which a substance changes from a solid to a liquid state.
What two factors determine if a substance will be a liquid?
The temperature of the environment and the melting and evaporation temperature of the substance.
What are two physical properties that can very even when the substance with these properties dose not change?
The dimensions: height, length, and width.
What are two physical properties that can that can vary when the substance with these physical properties that dose not change?
Two physical properties that can vary without changing the substance are temperature and pressure. For example, water can exist as a solid (ice), liquid, or gas (steam) at different temperatures and pressures, but it remains chemically the same H2O molecule.
What two determine the state of a substance?
Temperature and pressure
What 2 factors determine the state of a substance?
The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
What properties of substances can you observe and how do these properties determine the usefulness or hazards of a substance?
You can observe physical, chemical, and characteristic properties of a substance and can be used to determine the usefulness of a substance by, giving us information about the substance usually using our 5 senses which are physical properties. Or being able to describe the substances ability to undergo changes to its composition to produce one or more new substances, chemical property. Or even just being able to identify whether or not the substance is pure or not can help us determine if the substance is hazardous or not. two other properties I did not mention were the qualitative and the quantitative properties.
What are two or more substance combined?
properties
Are Name two categories used to classify properties matter?
Two categories used to classify properties of matter are physical properties and chemical properties. Physical properties can be observed or measured without changing the composition of the substance, while chemical properties describe how a substance changes into a new substance through a chemical reaction.

Density and melting point are two physical properties that do not depend on the size of a material. Density is the mass of a substance per unit volume, while the melting point is the temperature at which a substance changes from a solid to a liquid state.
What are Two factors which determine the distance a substance travels up the paper?
The two factors that determine the distance a substance travels up the paper in paper chromatography are the solubility of the substance in the solvent and the affinity of the substance for the paper.
What are two physical properties that can vary even when the substance with these properties does not change?
Density and temperature can both vary for a substance without changing the identity of the substance. The density of a substance can change with temperature, pressure, or the presence of impurities, while the temperature of a substance can change due to external factors like heating or cooling.
Name two categories used to classify properties of matter?
Two categories used to classify properties of matter are physical properties, which describe the characteristics that can be observed without changing the substance's chemical composition, and chemical properties, which describe how a substance interacts with other substances to form new substances.
1 Name two physical properties that characterize matter?
Density and state of matter (solid, liquid, gas) are two physical properties that characterize matter. Density refers to how closely packed the particles of a substance are, while the state of matter describes the arrangement and movement of particles.
What are the two type of changes?
The two types of physical properties are intensive and extensive. Intensive properties do not depend on the amount of a substance. An example of an intensive property is density. Extensive properties do depend on the amount of a substance. An example of an extensive property is mass.
When two substances combine chemically the properties of the products of what?
When two substances combine chemically, the properties of the products are different from those of the starting materials. This is because new chemical bonds are formed, leading to a different arrangement of atoms and different chemical properties.
