Which one of the following is the correct relation between the Kelvin temperature (T) and the Celsius temperature (tC)?
General KnowledgePhysics
- AThese are two independent temperature scales
- BT = tC
- CT = tC – 273.15
- DT = tC + 273.15
Explanation
The Kelvin and Celsius scales have the same unit size and differ only in their zero points. Absolute zero lies at −273.15 °C, so any Celsius reading is converted to Kelvin by adding 273.15. The correct relation is therefore T = tC + 273.15.
