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