Question

A liquid is frozen at absolute zero temperature. What happens to its

molecular motion?​

Answer 1

Answer:

The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only. ... Now, for zero absolute temperature, the velocity turns out to be zero, hence the entire system would come to a halt. So, the molecular motion would stop. Hence, the answer is Option C.
