The unit of absolute temperature is:
Correct answer: C. Kelvin
- A. Fahrenheit
- B. Centigrade
- C. Kelvin
- D. None of the above
Explanation
The Kelvin (K) scale is an absolute temperature scale, starting from absolute zero (0 K), which is the lowest possible temperature where particles have minimal thermal motion. The Kelvin scale is commonly used in scientific and engineering contexts, particularly in thermodynamics.

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.
