Question 10

Four rods of equal dimensions are made from different materials, W, X, Y, and Z. Each rod is heated at one end in an identical manner. The time taken for the temperature at the opposite end of each rod to rise by 2.0∘C2.0^\circ\text{C}2.0∘C is recorded as follows:

  • Material W took 42 s
  • Material X took 58 s
  • Material Y took 28 s
  • Material Z took 35 s
