Verified Answer :

it would be 1kg of gold at 20c

Answer:

here since temperature and mass is same so aluminium must have more thermal energy than gold

Explanation:

As we know that thermal energy stored inside the matter is given as

\(Q = m c\Delta T\)

now we know that

m = mass of the given substance

c = molar specific heat capacity

\(\Delta T\) = temperature with respect to zero degree C

now we know that

\(c_{Al} = 0.902 J/g ^oC\) = molar specific heat capacity of aluminium

\(c_{gold} = 0.129 J/g^oC\) = molar specific heat capacity of gold

So here since temperature and mass is same so aluminium must have more thermal energy than gold
