Question

A thermometer shows a reading of 37 degrees Celsius. What is the corresponding temperature in Kelvin?

This question was previously asked in
RRB NTPC 2025 Graduate Level CBT 1 Question Paper (25-Mar-2026) (Shift 3)
The correct answer is

310 K

To convert a temperature from degrees Celsius to Kelvin, you can use the following formula:

\(K = °C + 273.15\)

This formula is derived from the fact that 0 Kelvin is equivalent to -273.15 degrees Celsius.

  1. The given temperature in Celsius is 37°C.
  2. Substitute the value into the formula: \(K = 37 + 273.15\)
  3. Calculate the result: \(K = 310.15\)
  4. Since temperature in Kelvin is often rounded to the nearest whole number, we can write: \(K = 310\)

Therefore, the corresponding temperature in Kelvin is 310 K.

Conclusion: The correct answer is 310 K.

This step-by-step conversion shows why 310 K is the correct choice. The other options (300 K, 320 K, and 270 K) do not match the correct conversion result of 37°C to Kelvin.
