What is the measure of room temperature on the Kelvin scale?

Solution (By Examveda Team)

The correct answer is B: 298 K.
Here's why:
Room temperature is generally considered to be around 25 degrees Celsius (°C).
The Kelvin scale is related to the Celsius scale by a simple formula: Kelvin (K) = Celsius (°C) + 273.15.
So, to convert 25°C to Kelvin, we add 273.15 to 25, which gives us approximately 298.15 K.
Therefore, 298 K is the closest and most accurate representation of room temperature on the Kelvin scale.
The other options are incorrect:
98 K is extremely cold.
273 K is the freezing point of water (0°C).
373 K is the boiling point of water (100°C).
