Question

Q.7. The dimensions of the coefficient of thermal conductivity are
(A) M L T - 3 K - 1
(B) M L T - 2 K - 1
(C) M L T - 1 K - 1
(D) M L T - 2 K - 2

Answer 1

Answer:

Q- heat energy flowing in unit time

T -Temperature

t-time for which heat flows

A -Area of contact

We have k = Qd/(T1-T2)t.A

K= [ML²T-²][L]/[K][T][L²]

K= MLT-3 K-1
