Physical and chemical properties

In this video, we are talking about the differences between a physical property and a chemical property.

Physical properties are a measurable property that describes the state of a chemical compound.

Examples of physical properties

  • Color of the compound

  • Density

  • Volume

  • Luster (metals shine and nonmetals do not)

  • Brittleness (how easy is it to break that particular compound or element)

  • Concentration (basically the mass in terms of its volume; the density of the object)

  • Hardness (usually for metals)

physical and chemical properties

Chemical properties are a property that is observed during a chemical reaction. Here we are changing the identity of the chemical compound itself and a result creates something new. 

Examples of chemical properties

  • Flammability (how easy is it to catch on fire)

  • Toxicity

  • Solubility (how easy is it to dissolve a particular element or compound with water)

  • Oxidation (how easy is it to react or can it react with oxygen)

  • Corrosion (how easy is it to break it down with maybe acids or bases)

  • Heat of Combustion (the amount of heat that’s given off when a compound is basically exploded)

  • Enthalpy of Formation (how much energy is absorbed or released in order to form a compound)

  • Reactivity with water

  • Reactivity with acids

  • Radioactivity

Remember, physical properties have to do more with the state and appearance of an object and chemical properties have to do with its reactivity in a chemical reaction.

Jules felt a void in his life after his English degree from Duke, so he started tutoring in 2007 and got a B.S. in Chemistry from FIU. He’s exceptionally skilled at making concepts dead simple and helping students in covalent bonds of knowledge.
