The answer to your question is: Chemical Reaction.
Answer:
A. There is a temperature difference
Explation:
Whenever there is a temperature difference, heat transfer occurs. Heat transfer may occur rapidly, such as through a cooking pan, or slowly, such as through the walls of a picnic ice chest.
Magnesium, strontium and barium are a few of the elements that have the same properties as calcium. elements found in group 2 of the periodic table have similar properties to it.
Increasing order of magnitude of lattice energy is rbi <K2s< Mgs < Ga2O3.
Lattice energy is the energy change upon the formation of one mole of a crystalline ionic compound from its constituent ions. It depends upon the charges of the ion and the distance between the center of the ion when they are packed in the form crystal. Basically lattice energy is determined by the charge of the atom and the atomic radii of the atoms.
In Ga2O3, Ga has 3+ and O has 2- ions .so it has the lattice energy of 6.this is calculated by multiplying q1 and q2 .this attracts strongly.
In rbI , R has +1 and i has -1.so it ha lattice energy of -1.ther is no strong attraction nor lattice energy.
In Mgs, Mg has +2 and s has -2 .this is not as strong as Ga2o3 but stronger than rbi.
In K2S, k has =1 and s has 2-.this is stronger than rbi.
