Question

which of the following is not a physical property of water

a) has a boiling point of 100 degrees Celsius
b) is a colorless liquid
c) composed of hydrogen and oxygen
D) sugar dissolves in it

Answer 1

The answer is c. It is the chemical property of water

Answer 2

Answer: Option (c) is the correct answer.

Explanation:

The property which can be observed without any change in chemical composition of a substance is known as physical property.

For example, boiling point, color, shape, size, molecular weight, volume etc.

The property which can be observed by changing the chemical composition of the substance is known as chemical property.

For example, reactivity, oxidation state etc are the chemical properties.  

The options boiling point, colorless liquid, and sugar dissolve in it represents the physical property.

Whereas option (c) that is composed of hydrogen and oxygen represents the chemical composition. Thus, it is the chemical property and not a physical property.
