Trusted teacher: Thermal changes accompanying physical and chemical changes Thermal changes accompanying physical changes - melting temperature It is the temperature change when one mole of solute is dissolved in a given amount of solvent (The amount of heat energy absorbed or released when one mole of solute is dissolved in a given amount of solvent). During the dissolution process: two processes occur: A- Dissociation: the breaking of bonds (endothermic reaction) Sodium and chloride ions dissociate from the crystal lattice as a result of the ionic bond breaking. The energy absorbed to break the bond is called the heat of the crystal lattice (bond energy). - Crystal lattice temperature: It is the energy needed to break the bond between ions in the crystal lattice. B- Hydration: The dissociated ions bind with water molecules to form hydration ions (exothermic process). Rehydration temperature: It is the amount of heat released when hydrating ions bind to water molecules. If the crystal lattice temperature > heat of hydration Dilution temperature: It is the heat change per mole of solute when diluted from a concentrated solution to a dilute solution. (It is the heat change of one mole of solute when diluted in a large amount of water (about 1000 moles of solvent)). Sedimentation temperature: The amount of heat released when one mole of an insoluble substance is completely precipitated. - heat of combustion It is the amount of heat released when one mole of a substance is completely burned in an abundance of oxygen. (The reaction is always exothermic). Formation temperature: It is the amount of heat released or absorbed when one mole of a compound is formed from its elemental elements so that the elements are in their standard state. (at 25 °C, a pressure of 76 x g). Note: Heat of formation of the elements = zero

I would like to express my sincere appreciation for your excellent teaching in physics. My daughter, who is in 5th secondary at a French school here in Belgium, has greatly benefited from your clear explanations and structured approach Thank you very much for all your hard work.

I have had multiple lessons with Mohamed and each have been incredibly beneficial. He has been helping me learn chemistry from scratch and get it to an elevated level and after each lesson I find myself progressing substantially. Merci beaucoup.
