Answer:
One of the basic principles of chemistry is the electrostatic attraction between atoms or compounds. Electrons are on the outside of an atoms and that's where the charges come from and the interaction between those charges is what happens during a chemical bond. Therefore the answer would be electrons.

Raising its temperature by
Explanation:
The specific heat capacity of a substance is defined as the amount of energy needed to raise the temperature of 1 kg of a substance by .
The specific heat capacity of a substance essentially tells us how much energy is needed to heat the substance: the larger it is, the more energy is needed. The amount of energy needed to increase the temperature of a substance is given by
where
m is the mass of the substance
Cs is the specific heat capacity
is the temperature variation of the substance
Answer:
