Final answer:
Room temperature of 25°C is equivalent to 298.15 K when using the conversion formula K = °C + 273.15.
Step-by-step explanation:
Room temperature is usually considered to be 25°C. To convert this to kelvins (K), you can use the following conversion formula:
K = °C + 273.15
Applying this formula:
K = 25°C + 273.15
K = 298.15 K
Therefore, room temperature in kelvins is 298.15 K.
