Rank the following species according to the decreasing energy needed to raise the temperature of 10.0 g of the substance by 25.0 ∘c. rank from most to least energy needed. to rank items as equivalent, overlap them.

Answer 1) : To rank the species according to the decreasing energy needed to raise the temperature of 10 g of the substance by 25 °C, the oder of energy needed is given below as per their specific heat.

Which requires more energy as per their specific heats;

Answer 2)To rank items as equivalent, overlap them.

The average kinetic energy of the molecules after point D,

The average kinetic energy of the molecules from point B to point C,

The average kinetic energy of the molecules before point A.

the answer is c.the valence of the atoms combine .
