Question

Of the five, which is not a physical property?
A.Color
B.Phase
C.Odor
D.Boiling point
E.Reactivity with oxygen

Answer 1

Hint:There are two types of properties namely the physical and the chemical properties, the properties which change are reversible in nature are known as physical properties and the once which are irreversible are known as chemical properties.

Complete step by step answer:
The physical properties do not bring about any change in the physical constitution of the matter whereas the chemical properties bring about the chemical changes and the substance cannot be converted back to its initial form. The Color, phase, Odor, and boiling point are the physical properties of the matter. Thus the reaction of any substance with the oxygen is the chemical change since it changes the chemical constitution of the substance.
The main difference between the two types of changes is:

S.No.	Physical Change	Chemical Change
1	It is a temporary change.	It is a permanent change.
2	It only affects the physical property of the substance.	Both physical and chemical changes are affected.
3	Little or low adsorption of energy takes place.	High adsorption of energy takes place.
4	No new substance is formed.	New substance is formed.
5	Reversible in nature.	Irreversible in nature.

The binary compounds oxides are formed by the reaction between the oxygen and the other element. The reaction is also known as oxidation. For example: the reaction between the metal and oxygen results in the formation of the formation of the metal oxide.
Thus the option E is the correct answer.

Note:
The reactions in which the reduction and oxidation reaction takes place simultaneously are known as the redox reaction. Such reactions are commonly used in the cell reactions to know the reaction between the two half of the cells.
