medium

$l (x = 0$ થી $ x = l )$ લંબાઇના વાહકમાંથી ઉષ્મા પસાર થાય છે.તો તાપમાન વિરુધ્ધ અંતરનો આલેખ

A
B
C
D

Solution

(c) $\frac{{dQ}}{{dt}} = – KA\frac{{d\theta }}{{dx}}$ ( $\frac{{dQ}}{{dt}},$K and A are constants for all points

$ \Rightarrow \,\,d\theta \propto – dx$; i.e. temperature will decrease linearly with $x$ .
