Heat conduction

Classical Mechanics Level 3

A copper rod and an aluminium rod with the same cross sectional areas are joined as above, with the temperatures at each end maintained at $90°C$ and $0°C,$ respectively. Let $T$ be the temperature of the contact surface between the two rods. Let $Q_1$ and $Q_2$ be the quantities of heat passing through the cross sections of the copper and aluminium rods, respectively. What are the temperature $T$ and the relative values of $Q_1$ and $Q_2?$ (The thermal conductivity of copper is twice as large as that of aluminium.)

T=60°C

and

Q_1>Q_2

T=45°C

and

Q_1=Q_2

T=60°C

and

Q_1=Q_2

T=30°C

and

Q_1<Q_2
