Question

Explain why temperature below absolute zero is not possible?
Class 11( Physics)

Answer 1

Explanation:

Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gasreach their minimum value, taken as zero kelvins. The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion. The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, absolute zero is taken as −273.15° on the Celsius scale (International System of Units),[1][2] which equals −459.67° on the Fahrenheitscale (United States customary units or Imperial units).[3] The corresponding Kelvin and Rankinetemperature scales set their zero points at absolute zero by definition.

Answer 2

Explanation:

zero degree is the lowest thermodynamic point of temprature
