Question

Why does aluminum have a higher specific heat than gold?

Answer 1

Specific heat is the amount of heat energy a unit mass of a material must absorb to increase its temperature by 1°C. Each material has its own specific heat.
Specific heat is a physical property of matter. It is related to the excitation of the atoms and how well they hold heat. Aluminum atoms bind to each other tighter compared to gold atoms and resists an increase in atomic motion. also the
specific heat of Aluminum: 0.902 Joules/gram degree Celsius
specific heat of Gold: .129 Joules/gram degree Celsius.

Answer 2

Gold heats up about seven times faster than aluminium because gold has less (different) numbers of particles per unit mass. Gold has greater atomic mass (197 g/mol) and greater atomic radius (size) of an atom than aluminium (27 g/mol) metal. Amount of substance is equal to mass of substance divided with molar mass of substance.
