Kelvin is the SI Unit of measurement of temperatures. It is represented with the Unit Kelvin 'K'.
Temperatures can be converted from Celsius to Kelvin by adding 273 to the the Celsius Scale.
We have been given 3 temperatures here which are in the Celsius Scale.
25°C, 38°C and 66°C
To convert all of them to the Kelvin Scale, add 273 to all of them.
25 + 273 = 298 K
38 + 273 = 311 K
66 + 273 = 339 K

Understanding Temperature Conversion
To convert Celsius temperatures to Kelvin, you use the formula:
\[ K = °C + 273.15 \]
The Kelvin scale is an absolute temperature scale, meaning it starts at absolute zero.
Conversion Steps
1. Convert 25°C to Kelvin:
- \( K = 25 + 273.15 = 298.15 \) K
- Rounded to 298 K
2. Convert 38°C to Kelvin:
- \( K = 38 + 273.15 = 311.15 \) K
- Rounded to 311 K
3. Convert 66°C to Kelvin:
- \( K = 66 + 273.15 = 339.15 \) K
- Rounded to 339 K
Final Temperatures in Kelvin:
- 25°C = 298 K
- 38°C = 311 K
- 66°C = 339 K
Correct Sequence of Temperatures
When arranged in increasing order:
- 25°C = 298 K
- 38°C = 311 K
- 66°C = 339 K
Thus, the correct sequence is 298 K, 311 K, and 339 K. This matches option A.
Conclusion
The conversion process is straightforward and essential for various scientific applications. Always remember to add 273.15 when converting from Celsius to Kelvin, and round off the final results as needed. This ensures accurate representation of temperatures on the Kelvin scale.
