kelvin scale can be applied at very low temperature because
Correct answer: A. it is independent of nature of working substance
- A. it is independent of nature of working substance
- B. it is linear over a wide range of temperature
- C. it is based on triple point of water
- D. none
Explanation
This is indeed the key advantage of the Kelvin scale. Unlike the Celsius and Fahrenheit scales, which are defined based on specific properties of water (freezing and boiling points), the Kelvin scale uses the concept of absolute zero, which is the theoretical point where all thermal motion of atoms ceases. This makes it applicable to any substance, regardless of its individual properties

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
