Question 1
A metal bar 2 m long is heated at one end to 100°C while the other end is maintained at 20°C. If the thermal conductivity of the metal is 50 W/m·K, calculate the rate of heat transfer through the bar.
💡 Hint: Apply Fourier's equation and ensure to consider the dimensions correctly.
Question 2
Discuss the practical implications of conduction in everyday life. Provide at least three examples where conduction is important.
💡 Hint: Think about situations where you experience heat transfer directly or indirectly.
