Question 5 Specific Heat of Solid Substances Substance D Aluminum B silver; because it is a transition metal with the lowest specific heat value C Iron Copper Tin Given the specific heat information presented, which substance would make the BEST material to create a pan for cooking and why? D Specific Heat (J/kg°C) 899 443 385 213 Tin - because it has a low specific heat, which means it conducts heat the best. Aluminum - because it has a high specific heat, which means it conducts heat the best. Copper - because it has a mid-level specific heat, which means it is a good insulator. Iron - because it has a mid-level specific heat, which means it is a good conductor.
