Question

Quizplus · Accepted Answer

Absolute zero is defined as the temperature at which all thermal motion ceases, in other words, the temperature at which the disorderly motion of molecules reaches a minimum value. Therefore, at absolute zero, the volume of a gas becomes zero, which is represented by the intersection of a straight-line graph of V versus T (K) at the origin. Hence, the best choice is E.
