Answer:
B.
Explanation:
The particles that make up the aluminum bar are moving faster.
The bar of aluminum has a higher temperature than gold bar as the particles that make up the aluminum bar are moving faster.
What is temperature?
Temperature is a physical quantity that expresses hot and cold or a measure of the average kinetic energy of the atoms or molecules in the system.
What is thermal conductivity?
Thermal conductivity is the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area.
What are properties of aluminum?
Aluminum has low density. It has high thermal conductivity, has excellent resistance for corrosion and can be easily cast, machined and formed.
What are properties of Gold?
Gold has high corrosion resistance. It is good conductor of electricity.
Aluminum has high thermal conductivity than gold. So, the particles in the aluminum bar moves faster as compared to gold. Therefore, the temperature of aluminum bar is higher than gold bar.
