According to the third law of thermodynamics, at absolute zero the entropy of a system is constant or the entropy is equal to zero. The randomness in a system is referred to as its entropy.
When the temperature on the Kelvin scale is equal to zero, it is called an absolute zero condition.
Hence, the correct option is (c) " the third law of thermodynamics ".
<u>The Weight </u>is a vector whose magnitude is the product of the mass m of the object and the magnitude of the local gravitational acceleration. Its always directed toward the center of the Earth.
The work W done on an object by a constant force is defined as W = F. d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.
