Assertion : Absolute zero is the temperature corresponding to zero energy.
Reason : The temperature at which no molecular motion cease is called absolute zero temperature.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion
B. If both assertion and reason are true but reason is not the correct explanation of the assertion
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer

D

Explanation

Only the energy of translatory motion of molecules is represented by temperature. Other forms of energy such as intermolecular potential energy, energy of molecular relation, etc. are not represented by temperature. Hence at absolute zero, the translatory motion of molecules ceases but other forms of molecular energy do not become zero. Therefore absolute zero temperature is not the temperature of zero-energy. At absolute zero molecular motion ceases.
