Question

Which has more thermal energy, 1 kg of aluminum at 20°c or 1 kg of gold at 20°c

Answer 1

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

Answer 2

It would be 1kg of gold at 20c
