Answer: Mineral A changed because Molecular energy transferred is equal or greater than than its Activation energy
Mineral B didn't change because Molecular energy transferred is less than its Activation energy.
Explanation:
The molecules of Mineral A has been disturbed by the addition of energy causing a change and the entropy is increased. The Molecules of Mineral B has not been disturbed because the residual energy has not been overcome and therefore yielding no visible change
