AnswersDrivephysical and chemical properties. Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples.
Consequently, how chemical and physical properties are alike and different?
(compare and contrast) (Physical and chemical changes are similar because matter experiences a change in state, Physical changes are different because matter remains the same substance, just in a different state, whereas chemical changes change the matter forever).

What are some examples of chemical properties?
Examples of chemical properties of a substance can include:
- toxicity.
- oxidation.
- flammability.
- heat of combustion.
- enthalpy of formation.
- chemical stability under specific conditions.
- radioactivity.

What is the difference between the physical and chemical properties of a substance?
A physical property is an aspect of matter that can be observed or measured without changing its chemical composition. Examples of physical properties include color, molecular weight and volume. A chemical property may only be observed by changing the chemical identity of a substance.
4
What is an example of a chemical property?
Some common physical properties are odor, density, melting point and boiling point, while some common chemical properties are heat of combustion, enthalpy of formation, toxicity, and flammability, each of which will be covered in this lesson.
5
What is the definition of chemical properties?
Chemistry. a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed: Combustibility is an important chemical property to consider when choosing building materials.
6
Is a luster a chemical or physical property?
Physical properties can be broken down into extensive and intensive properties. Intensive properities can help you identify a substance. Likewise, melting point is also an intensive property. Other examples of intensive properties include density , solubility, color, luster, freezing point and malleability.
7
What is the definition of a chemical property?
A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. They can also be useful to identify an unknown substance or to separate or purify it from other substances.
8
Is reactivity a physical or chemical properties?
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
9
What are the physical and chemical properties of metals?
Metals are dense, shiny, good conductors of heat and electricity, and easily lose electrons in chemical reactions. Nonmetals are not dense, dull, do not conduct heat and electricity, and tend to gain electrons. Metalloids are elements that have properties of both metals and nonmetals.
10
Is flammable a chemical or physical property?
Flammability is a chemical property because combustion is a chemical change. A chemical change is a process in which one or more substances are converted into one or more new substances with different properties. Gasoline is highly flammable. Flammability is a measure of how easily something will burn.
11
What are the physical and chemical properties of matter?
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.
12
Is acidity a chemical property?
Acidity is a chemical property because it is a measure of the presence of a particular chemical, the H+ ion (hydrogen with a positive charge. Water, H2O, is a combination of H+ and OH-, and is neutral, both electrically, and in pH, the measure of acidity. This quality is fundamental to many, many chemical reactions.
13
What are the physical and chemical properties?
Physical properties are those that can be observed without changing the identity of the substance. The general properties of matter such as color, density, hardness, are examples of physical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.
14
What is the definition of a chemical property of matter?
Definition of Chemical Properties of Matter. Some properties of a substance are not as obvious, unless the substance has changed composition as a result of a chemical reaction. A chemical property is the ability of a substance to combine with or change into one or more other substances.
15
What is an example of a chemical change?
Combustion reactions, such as a burning candle, are also examples of the chemical change through the combination of wax and oxygen in a reaction that produces heat, light, and carbon dioxide. Decomposition, the opposite of combination, occurs when a single substance breaks down into two or more different substances.
16
How are elements and compounds similar and how are they different?
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. A compound can be separated into simpler substances by chemical methods/reactions.
17
How are physical and chemical changes similar?
(compare and contrast) (Physical and chemical changes are similar because matter experiences a change in state, Physical changes are different because matter remains the same substance, just in a different state, whereas chemical changes change the matter forever).
18
What is a physical property in chemistry?
Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
19
Is combustibility a chemical property?
Combustion, being the exoteric reaction of a material, typically atmospheric oxygen, is absolutely a chemical reaction, so "Combustibility" is a chemical property, or sort of. (At the flash point, the vapor may cease to burn when the ignition source is removed.)
20
What is a chemical change?
Chemistry. a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance: The formation of rust on iron is a chemical change.
