Question

Two bodies A and B are at temperatures - 100 °C and 173 K respectively. The body at higher temperature is

• A. A
• B. B
• C. Both are at same temperature
• D. None of these

Answer 1

The Correct Option is C

Correct answer: B

Explanation: 
To compare the temperatures of the two bodies, we need to convert the temperatures into the same scale. Let's convert both temperatures to Kelvin (K). - Temperature of A: -100°C \[ T_A = -100°C + 273.15 = 173.15\ K \] 
- Temperature of B: 173 K (already in Kelvin) Now, comparing the temperatures: 
- Body A is at 173.15 K. - Body B is at 173 K. 

Therefore, Body A is slightly warmer than Body B. Hence, Body A has a higher temperature. The correct answer is Body A is at a higher temperature.
