Explanation:

Why is the unit of temperature called a fundamental unit

Kelvin is a fundamental unit! 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. Time is said to be a fundamental unit because it is not dependent on one or more units.

Find the fundamental units involved in the following derived u

(a) Newton - kgms−²

(b) Watt - kgm² s−³

(c) Joule - kgm² s−²

(d) Pascal - kgm−¹s−²
