Question

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

Answer 1

it would be 1kg of gold at 20c

Answer 2

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

Step-by-step 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
