Verified step by step guidance1
Identify the formula to convert Celsius to Kelvin, which is given by: \(K = {\degree}C + 273.15\).
Note the given temperature in Celsius, which is 20 °C.
Substitute the Celsius temperature into the formula: \(K = 20 + 273.15\).
Perform the addition to find the temperature in Kelvin (do not calculate the final value here, just set up the expression).
Understand that the Kelvin scale starts at absolute zero and is used in scientific measurements to avoid negative temperatures.
