This question was previously asked in
RRB NTPC 2024 Undergraduate CBT 1 Question Paper (29-Aug-2025) (Shift 1)
The correct answer is

300 K

To convert temperature from Celsius to Kelvin, we use the formula:
K = °C + 273.15

Let's convert 27°C to Kelvin:

K = 27 + 273.15 = 300.15 K

For simplicity in many practical applications, the Kelvin value can be considered without decimals when dealing with approximately whole numbers of Celsius. Therefore, 27°C converts approximately to 300 K under usual rounding considerations.

The correct answer is: 300 K
