What is the equivalent of 0C in Kelvin?
A
273 K
B
237 K
C
-273 K
D
-237 K
Explanation: 

Detailed explanation-1: -Therefore, water freezes at 273 kelvins, it follows that 0 degrees celsius equals 273 kelvins and that 0 kelvin equals minus 273 degree celsius.

Detailed explanation-2: -Kelvin is the primary unit of temperature measurement in the physical sciences. 0 degree Celcius converted into Kelvin scale is 273.15 K.

Detailed explanation-3: -absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale.

Detailed explanation-4: -273 °C to K = 546.15 Kelvin Just remember that the temperature difference is 273.15, and that the value in the unit of measurement K is the bigger.

Detailed explanation-5: -Celsius vs Kelvin The major difference is that when water freezes, a Celsius thermometer will read 0°C, and a Kelvin thermometer will read 273.15 K. The scales differ by 273.15. Thus, to convert from °C to K simply add 273; if a thermometer reads 31°C then the temperature in Kelvin is 304K.
