What is the definition of boiling point in chemistry and how does it relate to the physical properties of a substance?
The boiling point in chemistry is the temperature at which a substance changes from a liquid to a gas. It is a physical property that is unique to each substance and can be used to identify and characterize it. The boiling point is influenced by the strength of intermolecular forces within the substance, with stronger forces requiring higher temperatures to overcome and boil.

How does freezing chemistry impact the properties of substances?
Freezing chemistry can impact the properties of substances by causing them to change in physical state, such as from a liquid to a solid. This change can affect the substance's density, volume, and structure, leading to alterations in its properties like hardness, brittleness, and conductivity.
What are chemistry properties?
Chemical properties refer to the characteristic behavior of a substance when it undergoes a chemical reaction, such as its ability to react with other substances or its stability under certain conditions. These properties are determined by the substance's chemical composition and structure. Examples of chemical properties include flammability, acidity, reactivity, and toxicity.
What is the significance of the variable "m" in chemistry and how does it relate to chemical reactions or properties?
In chemistry, the variable "m" often represents the mass of a substance. It is significant because mass plays a crucial role in chemical reactions and properties. The mass of reactants determines the amount of products formed in a reaction, and the mass of a substance can affect its physical and chemical properties.
Do all samples of a substance have different physical properties?
Yes, two substances can have the same physical property. For example, both water and ethanol are clear. For this reason, multiple properties must be examined when determining the identity of a substance.
What arr some of the physical properties of a pure substance?
Physical properties of a pure substance include color, melting point, boiling point, density, solubility, and conductivity. These properties can be used to identify and characterize the substance.
What are the physical properties of the substance?
The physical properties of a substance are the substance's physical appearance. This includes the color, shape, weight, width, and height.

How can knowing the physical properties of a substance be useful?
The physical properties of a pure substance can be used to identify it. A pure substance is an element or a compound, not a mixture.
How is a physical change related to a substance physical properties?
a physical change is a change in any physical property of a substance, not in the substance itself

What is the research on the physical and chemical properties of seawater?
chemistry
Is magnetic quality a chemical or a physical property?
physical property
What is a Substance without reference to another substance?
physical properties
Compare and contrast chemical and physical properties?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
How can you separate a pure substnace?
A pure substance can be separated by physical methods such as distillation, filtration, or chromatography depending on the properties of the substance. These methods exploit differences in physical properties such as boiling point, solubility, or size to isolate individual components of the substance.
