The coefficients of thermal conductivity of copper, mercury and glass are respectively K c , K m and K g such that K c > K m > K g . If the same quantity of heat is to flow per second per unit area of each and corresponding temperature gradients are X c , X m and X g , then
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Hence If 
, then
because higher K implies lower value of the temperature gradient.
