Electromagnetism
Theoretically it is a branch of physics that contains two sources. Either electrically charged particles or the behavior between Neutrons and protons etc.
Answer:
When two substances having different temperatures are introduced or kept together, heat energy, Q, flows from a substance at higher temperature to a substance at lower temperature. Also, heat continues to be transferred until their temperatures are equalized, at which point the substances are in thermal equilibrium. In a closed system, the amount of energy lost is equal to but opposite the amount of energy gained.
Explanation:
The substance which is a combination of different atoms is a compound.
at 60ºC:
106 g KNO₃ -------------- 100 g (H₂O)
? g KNO₃ ------------------ 50.0 g (H₂O)
mass KNO₃ = 50.0 * 106 / 100
mass KNO₃ = 5300 / 100
<span>= </span>53 g of KNO₃

It is because the space between particles decreases but also looses energy at the same time.
