Question
Two plates of equal areas are in contact with each other. Their thickness are 2 cm ans 3cm respectively. Temperature of external surface of first plate is - 25oC and that of external surface of second plate is 25oC What will be temperature of contact surface if the plates :-
(i) Are of same material (ii) Have thermal Conductivity ratio 2 : 3
(i) Are of same material (ii) Have thermal Conductivity ratio 2 : 3
Options
A.(i) - 5oC (ii) 0oC
B.(i) 5oC (ii) 0oC
C.(i) 0oC (ii) - 5oC
D.None of these
