WebBoth extensive and intensive properties are physical properties, which means they can be measured without changing the substance's chemical identity. For example, the freezing point of a substance is a physical property: when water freezes, it's still water (H 2 O)—it's just in a different physical state. WebMercury Physical Properties. Mercury metal can be frozen and changed into a solid at a temperature of –38.85°C. It can be transformed into a gas when boiled at 365.6°C. The density of mercury is 13.59 grams per cubic …

WebHydrogen, H2, is a colorless, odorless gas. Hydrogen is easily ignited. Once ignited it burns with a pale blue, almost invisible flame. The vapors are lighter than air. It is flammable over a wide range of vapor/air concentrations. Hydrogen is not toxic but is a simple asphyxiate by the displacement of oxygen in the air.
