Physical vs Chemical Properties – Explained


Millings and Today, We’re Going to Learn About Physical versus Chemical Properties so let’s Jump right in and Take a Physical Properties it Says Right Here our Properties of Matter that described the Physical Characteristics of A substance and not how the Substance behaves Chemically Alright so Physical Properties will Tell you how that Substance behaves Physically but not Chemically for example if We said that aluminum Foil Is Malleable what does that mean what Does the word Malleable mean Where well it means? That the metal Is Has the Ability to be Hammered Into thin Sheets so we can? We Can Take Aluminium and Pound it down Into or Hammer it down Into thin Sheets so That’s Not, Telling Us how this Aluminium Foil is going to react With something Else that’s Just Telling Us how It’s going to change Physical Form so malleability or malleable is a physical Property of Matter if We Take a look at Ductile or Ductility That is the Ability of metal has to be turned Into wire for example if We Said Copper Is [matt] is Ductile? That Would be a Physical Property of that of that Copper that’s not Telling us how It’s going to Chemically react With something Else if We said The Boiling Point of Water Is a Hundred degrees Celsius Boiling Point Is a physical Property it doesn’t tell Us how that that Water Is going to react or change Chemically Into Something Else it’s Just Telling Us that at a Hundred degrees This This Liquid Substance Is going to turn Into Water Vapor Which Is a physical Change all right if We said the Frequency of this wave iS 20 Hertz Well then that Would Be a physical Property of This wave Frequency is the amount of Wavelengths that Pass A given Point Every Single Second so that [Would] be a physical Property [if] We talked about the Viscosity of Fluids how some Fluids are More Viscous Than Others for Example Honey Is more Viscous Than Water as a higher Viscosity that, would be A Physical Property of That and Last but not least Solubility We said Salt and Sugar Are Soluble in Water that Is Going to be A? Physical Property of Those Substances That Does not tell Us how the salt or sugar Is Going to behave Chemically [Alright] so Physical Properties Are Properties that describe the Physical Characteristics of a substance and not how this Substance behaves Chemically Let’s Take A Look Now at chemical Properties, okay Chemical Properties Are A little Different Chemical Properties [Or] [Properties] of a substance [that] describe how That Substance Is chemical Composition will Change given a Certain Specific Set of Conditions [Alright] so if We Take a look at A few examples of Chemical Properties if I said Gasoline is Flammable That Tells you how that Gasoline is going to react When Exposed to an Open Flame if We Said a substance, was? Radioactive That Tells you how the Nucleus of that atom is going to change Over Time if We said that something is corrosive Battery Acid is Corrosive? That Tells you how that acid Is Going to behave Chemically if We Said that [A] chemical Was A an Oxidizer which means that it has the Ability to Strip an Electron off Another Substance Well that Would be A chemical Property of that Substance right so things like Flammability Radioactivity A substance Being an Oxidizer or corrosive These are all chemical Properties if We Said That oxygen is Combustible? Once Again That tells Us how oxygen is going to react With an Open Flame Right it’s going to be Converted Into Carbon Dioxide and Water Vapor if We said something is Toxic that too is A chemical Property? If We said tnt is explosive That too? Would be A? Chemical Property of That Substance and Last but not least if We Said that something is Pyrophoric that Means that that Substance Has the Ability to ignite When Exposed to air so that will be A chemical Property as Well so chemical Properties Are Properties of a substance [that] describe how that Substances Chemical Composition will Change given a specific set of Conditions so Let’s Take a look at A few [examples] and See if You Can Determine Whether they are Physical or chemical Properties of Matter All right Let’s Take a look at this little List Here and Determine if They are Physical Or chemical Properties and I advise that You go Ahead and Pause this Video at this Point and Work Through These Yourself See if you Can Figure Out if These are Physical or chemical Properties so Freezing Point like We just got [then] Saying that’s going to be a physical Property [of] Matter That’s Not, Telling Us how, that’s since Is going to change Chemically right if Something is Combustible Well that’s going to be A chemical change right if We Said That oxygen Is? Combustible That Tells Us that oxygen Over Time is going to change the Carbon Dioxide and Water Vapor right if We Said that Sodium Metal Is Water reactive Which it is when you Throw it in Water There’s A very violent Reaction it’s A Chemical Change Has Taken place so that Water Reactivity, Would be A chemical Property of Say Sodium [Alright] if We said something as Viscous [that] Refers to? Fluids Ability to Flow so that’s Going to be a physical Property If We said that [a] substance was Toxic that, also would be A I’m sorry that, Would be A chemical Property? A condensation Point right if We Said that Water Begins to Condense and Turn Back Into Our water [Vapour] condenses at 100 degrees Celsius and Turns Back Into Liquid that is going to be a physical Property This is [A] cool, Property all right Something is Pyrophoric that means it ignites an Air that’s Going to be A chemical Property If Something is corrosive Like Battery Acid that’s Going to be a chemical Property of That Substance and Last but not Least If We said that The melting Point of Ice is Zero degrees Celsius that [too] will be [a] physical [Property]? That’s Not, Telling Us how That Ice is going to behave Chemically? All right so that is a Physical and Chemical Properties in A nutshell if You like what you see go Ahead and Click the little dezz nuts u know the way dezz nuts
