Question

Zero degree Kelvin is equal to
1. 100 degree centigrade
2. -273 degree centigrade
3. Zero degree centigrade
4. 273 degree centigrade

Answer 1

Correct Answer - Option 2 : -273 degree centigrade

Concept:

Absolute zero temperature:

• The lowest temperature at which there is no heat energy remained in the body is called an absolute zero temperature of that body.
• Degree Celsius and Kelvin are the standard units of the temperature.

The relation between Degree Celsius (C) and kelvin (K) is given by:

K = C + 273.15°C

EXPLANATION:

Absolute temperature, K = 0 kelvin

K = C + 273.15°C

C = 0 – 273.15 = - 273.15°C

C =  - 273.15°C
