Vedclass · Answer

(C) Heavy water $(D_2O)$ is used as a moderator in nuclear reactors to slow down fast neutrons.It is obtained as a by-product in the fertilizer industry during the production of hydrogen.It is used in the study of reaction mechanisms by using $D$ as a tracer.The dielectric constant of ordinary water $(H_2O)$ is $78.39$,while that of heavy water $(D_2O)$ is $78.06$ at $298 \ K$.Therefore,the statement that heavy water has a higher dielectric constant than water is $INCORRECT$.
