GENERAL KNOWLEDGE

Detailed explanation-1: -Among the options given, the temperature is a fundamental quantity and it is a measure of the degree of hotness or coldness of a body. It is the degree or intensity of heat present in a substance or object. It is represented according to a comparative scale and is measured by a thermometer.

Detailed explanation-2: -In Physics, Length, Mass, Time, Electric Current, Thermodynamic Temperature, etc are examples of Fundamental Quantities.

Detailed explanation-3: -It’s a lot easier to measure temperature than to measure the motion of component particles. Hence, we can accept it as a fundamental quantity.

Detailed explanation-4: -Hence, (c) is the correct option i.e the weight is not the fundamental quantity.

Detailed explanation-5: -The present SI has seven base quantities: time, length, mass, electric current, thermodynamic temperature, amount of substance, and luminous intensity.
