Final answer:
The temperature of scalding water at 54 °C converted to Kelvin is 327.15 K, which is option (a).
Step-by-step explanation:
To convert the temperature of scalding water from Celsius to Kelvin, we add 273.15 to the Celsius temperature. The provided Celsius temperature is 54 °C. So the conversion to Kelvin would be:
K = °C + 273.15
K = 54 °C + 273.15
K = 327.15
Therefore, the temperature of the scalding water in Kelvin is 327.15 K, which corresponds to option (a).
