The unit of temperature in base unit is:
Correct answer: C. Kelvin
- A. Celsius
- B. Degree
- C. Kelvin
- D. Fahrenheit
Explanation
Kelvin: Kelvin (K) is the base unit of temperature in the International System of Units (SI). It is an absolute temperature scale where 0 Kelvin represents absolute zero, the theoretical lowest possible temperature where all molecular motion ceases. Kelvin is commonly used in scientific and technical applications, particularly in physics and chemistry.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
