Answer:
298.15 Kelvin.
Step-by-step explanation:
To convert Celsius to Kelvin, you need to add 273.15 to the Celsius temperature.
So, to convert 25 degrees Celsius to the Kelvin scale:
Kelvin = Celsius + 273.15
Kelvin = 25 + 273.15
Kelvin = 298.15
Therefore, 25 degrees Celsius is equivalent to 298.15 Kelvin.
