May 23, 2023 · Without the heating caused by the greenhouse effect, Earth’s average surface temperature would be only about −18 °C (0 °F). On Venus the very high concentration of carbon dioxide in the atmosphere causes an extreme greenhouse effect resulting in surface temperatures as high as 450 °C (840 °F).

Basically, physical properties are those which you can observe and measure without changing the chemical identity of your sample. Physical properties are used to describe matter and make observations about it. Examples of physical propertiesinclude color, shape, position, volume and boiling point. Physical properties may be subdivided into intensiv...
Chemical properties, on the other hand, reveal themselves only when the sample is changed by a chemical reaction. Examples of chemical propertiesinclude flammability, reactivity and toxicity.
Would you consider solubility to be a chemical property or a physical property, given that ionic compounds dissociate into new chemical species when dissolved (e.g., salt in water), while covalent compoundsdo not (e.g., sugar in water)?
