Question

Properties such as shape, size, colour, and state of substance are called it is:
A. Chemical properties
B. Physical properties
C. Chemical changes
D. None of these

Answer 1

Hint: Properties of a matter are the qualities that enable us to distinguish one sample of matter from another. These qualities are generally classified under chemical and physical properties based on whether a change of chemical nature is required to observe the property.

Complete step by step answer:
 Physical properties are the properties that can be measured or observed without changing the chemical nature of the substance. We use these properties to describe the matter such as its colour, conductivity, shape, size, state, volume, etc.
Also, physical properties can be further classified as
Intensive properties: These are the properties that remain the same irrespective of the amount of the substance. Such as Density, color, conductivity, luster
Extensive properties: These are properties that differ with the amount of substance such as mass and volume.

So, the correct answer is Option B .

Additional Information:
The properties that can be observed at the time of chemical reaction are known as chemical properties and they result in a change in the chemical composition of the substance. Some of the examples of chemical changes are Flammability, Oxidation. Reduction, Hydrolysis, Burning. Also, the processes involving chemical changes are known as a chemical reaction and the substances involved in a chemical reaction are known as Reactants and resultant substances are known as products.

Note: Physical properties of a substance can be observed just by touching or viewing a substance and does not need any special procedures. Also, the changes involving physical properties of the substance, i.e. physical changes are generally reversible.
