Answer:
Explanation for this statement has been given below.
Step-by-step explanation:
![T(K)=T(^(0)\textrm{C})+273](https://img.qammunity.org/2020/formulas/chemistry/college/rgqedbfkh5zdpktqx4e8y70wvnzc8sf2hy.png)
To convert temperature in Celsius scale, we have to add 273 with the given temperature in Celsius. Therefore it is an one step conversion.
![T(^(0)\textrm{F})=1.8T(^(0)\textrm{C})+32](https://img.qammunity.org/2020/formulas/chemistry/college/kzedox41ialirpnh7qo9fwehboslbjxvf0.png)
To convert temperature in Fahrenheit scale, we have to first multi given temperature in Celsius scale with 1.8 and then add 32 with it. Therefore it is a two step process.
Hence a one-step conversion is sufficient to convert a temperature in the Celsius scale into the Kelvin scale, but not into the Fahrenheit scale.
