Answer:
Step-by-step explanation:
The metal that will reach 20 degrees above room temperature first depends on its specific heat capacity and other thermal properties. Specific heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius (or Kelvin).
Metals generally have lower specific heat capacities compared to non-metals, meaning they heat up and cool down more quickly. However, without knowing the specific metals in question and their specific heat capacities, it's difficult to determine which metal will reach 20 degrees above room temperature first.
In general terms, the metal with the lower specific heat capacity will heat up faster, but the specific heat capacity is not the only factor at play. The thermal conductivity, density, and other properties of the metals also influence how quickly they heat up. Additionally, the initial temperatures of the metals and the rate of heat supply are important factors.
If you provide more information about the specific metals and their properties, it would be possible to make a more accurate prediction.
