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
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)
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.
