请以资深中国初中化学教师的身份，讲解二氧化碳的物理性质这一节课，要求讲解过程图文并茂，用不同的颜色标注，语言风格风趣幽默，简单易懂。最好动画丰富一点，直观一点。动画样式参考我给的图。---**Extraction Content:** * **Title:** 二氧化碳的物理性质 (Physical Properties of Carbon Dioxide) * **Textual Information:** * 无色无味的气体 (Colorless, odorless gas) * PCO₂ > P空气 (Density of CO₂ > Density of air) * PCO₂ > P空气 (Density of CO₂ > Density of air) * 密度比空气大 (Density is greater than air) * 不燃烧也不支持燃烧 (Does not burn and does not support combustion) * 溶于水 (Dissolves in water) * **Labels:** * 二氧化碳 (Carbon Dioxide) - on the gas jar (left and right illustrations). **Chart/Diagram Description:** The image contains three simple illustrations and a cartoon character related to the physical properties of carbon dioxide. * **Illustration 1 (Left):** A sealed gas jar labeled "二氧化碳" (Carbon Dioxide). This represents a sample of carbon dioxide gas. * **Illustration 2 (Right):** A gas jar labeled "二氧化碳" is depicted tilting and pouring its contents into a beaker. The beaker contains two lit candles at different heights. The lower candle's flame appears extinguished, while the upper candle's flame is still lit. Blue circles (possibly representing CO₂) are shown near the lower candle. This illustrates that carbon dioxide is denser than air and does not support combustion. * **Illustration 3 (Bottom):** A horizontal glass cylinder or tube partially filled with liquid. Bubbles are shown inside, suggesting gas interacting with the liquid. This illustration is positioned below the text "溶于水" (Dissolves in water) and likely represents the solubility of carbon dioxide in water. * **Cartoon Character:** A cartoon character with glasses and an orange shirt is positioned in the center, between the main illustrations.
