Answers
Answer:
physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties
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.
physical 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.

Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Gas Bubbles Appear. Gas bubbles appear after a chemical reaction has occurred and the mixture becomes saturated with gas. ...
Formation of a Precipitate. ...
Color Change. ...
Temperature Change. ...
Production of Light. ...
Volume Change. ...
Change in Smell or Taste.
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
true.Many chemical reactions can occur in both directions. These reactions are called reversible reactions. Not only can the reactants change to the products, but the products can change back to the reactants, at least under certain conditions. ... This shows that the reaction can go both ways.
In a chemical reaction, the atoms and molecules produced by the reaction are called products. ... In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products
No, melting of chocolate is not a chemical change.It is a physical change. This is because when a chocolate melt , no new substance is form and the melting of chocolate can be reversed by freezing.
