Question

The values of celsius scale can be converted to Kelvin scale by ____________.

• A. subtracting 273
• B. subtracting 373
• C. adding 273
• D. adding 373

Answer 1

The correct option is C

adding 273

The explanation for the correct option:

• Measurement unit of temperature: $0°\mathrm{C}=273\mathrm{Kelvin}$
• If the temperature value is Celsius - convert it into a kelvin by adding 273.
• If the temperature value is on the Kelvin scale - convert it into Celsius by subtracting 273.

The explanation for the incorrect option:

• Subtracting 273: It is used in converting Kelvin to Celsius
• Subtracting 373: It is not used in any scale for conversion
• Adding 373: It is not used in any scale for conversion

Hence, the correct option is C.
