← A copper rod and an aluminium rod, each 0.50 m long with a cross-section of 2.0 cm², lie side by side between a 100 °C bath and a 0 °C bath. How much heat flows through the pair each second? (k: copper 385 W m⁻¹K⁻¹, aluminium 205 W m⁻¹K⁻¹.)The Sun's surface gives out 6.3 × 10⁷ W on every square metre. Treating it as a black body, what is its surface temperature? (σ = 5.67 × 10⁻⁸ W m⁻²K⁻⁴.) →
