The thermal conductivites of copper, mercury and glass are respectively K_(C),K_(M)andK_(G) such that K_(C)gtK_(M)gtK_(G). If the same quantity of heat flows per second per unit area of each and the corresponding temperature gradients are X_(C),X_(M)andX_(G) then

The thermal conductivites of copper, mercury and glass are respectivel

1.	The thermal conductivites of copper, mercury and glass are respectively K_(C),K_(M)andK_(G) such that K_(C)gtK_(M)gtK_(G). If the same quantity of heat flows per second per unit area of each and the corresponding temperature gradients are X_(C),X_(M)andX_(G) then
Answer» `X_(C)=X_(m)=X_(g)` `X_(c)LT X_(m)lt X_(g)` `X_(c)gt X_(m)gt X_(g)` `X_(m)lt X_(c)lt X_(g)` ANSWER :B
