The unit name of temperature is:
Correct answer: A. Degree or Kelvin
- A. Degree or Kelvin
- B. Candela
- C. Mole
- D. Kilogram
Explanation
Temperature can be measured in either degrees Celsius (°C) or Kelvin (K). The degree Celsius is a unit of temperature in the Celsius scale, where 0°C is the freezing point of water and 100°C is the boiling point of water at standard atmospheric pressure. The Kelvin, on the other hand, is the SI unit of temperature. It is an absolute temperature scale with the same increments as degrees Celsius, but its zero point (absolute zero) is 0 K, representing the point at which all molecular motion ceases.

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.
