Question

Give reasons:- Explain -273.15 K is the theoretically lowest temperature.​

Answer 1

Explanation:

The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, absolute zero is taken as −273.15 degrees on the Celsius scale (International System of Units), which equals −459.67 degrees on the Fahrenheit scale (United States customary units or Imperial units).

Answer 2

Explanation:

Lowest attainable temperature is absolute zero, i.e., 0K=−273.15

∘

C

∵Temperature in kelvin=+273.15 Temperature in degree celsius

This is the relationship between kelvin and degree temperatures.

Therefore, the size of each degree on Kelvin scale is the same as that on celsius scale.
