عرض الدرس (Lesson Presentation)

• Heat Exchange: The spontaneous flow of thermal energy from a higher-temperature body to a lower-temperature body upon contact.

• Thermal Equilibrium: The state in which two contacting bodies (or a system and surroundings) reach equal temperatures.

• Cessation of Heat Transfer: Upon reaching thermal equilibrium, net thermal energy transfer between the two contacting bodies ceases.

• Conditions for Thermal Equilibrium: Direct thermal contact, initial temperature difference, and continued heat exchange until temperatures equalize.

الأنشطة والتقييمات (Assessments & Activities)

• الأداء الصفي (Classroom Performance): Students record temperature readings of hot and cold water before and after mixing to determine the equilibrium temperature.

• الواجب المنزلي (Homework): P. ........

عرض الدرس (Lesson Presentation)

• Covalent Bond: A chemical bond formed between non-metal atoms through sharing a number of electrons to complete their outer energy levels.

• Types of Covalent Bonds:

  • Single Covalent Bond: Each atom shares 1 electron (1 shared pair), e.g., Hydrogen molecule (H2\text{H}_2H2​) and Water (H2O\text{H}_2\text{O}H2​O).

  • Double Covalent Bond: Each atom shares 2 electrons (2 shared pairs), e.g., Oxygen molecule (O2\text{O}_2O2​).

  • Triple Covalent Bond: Each atom shares 3 electrons (3 shared pairs), e.g., Nitrogen molecule (N2\text{N}_2N2​).

• Properties: Formed between non-metals, producing elemental or compound molecules.

الأنشطة والتقييمات (Assessments & Activities)

• الأداء الصفي (Classroom Performance): Students construct a comparison table between single, double, and triple covalent bonds regarding shared electrons and an example for each.
