Thermal conductivity of aluminium, copper and stainless steel increases in the order

Options

  1. ACopper < Aluminium < Stainless Steel
  2. BStainless Steel < Aluminium Copper
  3. CAluyminium < Copper Stainless Steel
  4. DCopper Stainless Steel Aluminium

Correct answer

B. Stainless Steel < Aluminium Copper

Step-by-step solution

Among the three aluminium, copper and stainless steel copper is the best conduction of heat. Thermal conductivity (in W/m K) for copper, aluminium and stainless steel is 385,205 and 50.2 respectively.
