Fisico Quimica 10 Ano

O 10.º ano em Físico-Química é o início de uma viagem incrível: desde a imensidão do Universo e a escala atómica até à forma como a energia move o mundo.

| Mistake | Consequence | Correction | | :--- | :--- | :--- | | | Entire problem is marked wrong. | Always write units (J, V, A, g, etc.) in every step. | | Using Celsius in gas laws or energy equations | In thermodynamics, formulas require Kelvin. | Convert: ( T(K) = T(°C) + 273 ). | | Confusing atomic number with mass number | Wrong element identification. | Z = protons (defines element); A = protons + neutrons. | | Assuming all non-metals form covalent bonds | Misidentifying ionic vs. covalent. | Check electronegativity difference > 1.7 generally indicates ionic bond. | | Ignoring intermolecular forces | Incorrect prediction of boiling/melting points. | Always ask: "What forces exist BETWEEN these molecules?" | Fisico Quimica 10 Ano
