Final answer:
To convert 51°C to Kelvin, add 273.15 to the Celsius temperature, which results in 324.15 K. Kelvin does not use the 'degree' term, so the temperature is expressed as 324.15 K.
Step-by-step explanation:
To convert the temperature from degrees Celsius to Kelvin, you add 273.15 to the Celsius temperature. Therefore, to convert 51°C to Kelvin, we use the following equation:
K = 51°C + 273.15
= 324.15 K
Thus, the temperature of 51°C is equal to 324.15 Kelvin. Remember that when converting to Kelvin, the unit 'degree' is not used; it is simply expressed as K.
