0:06Millings and Today, We're Going to Learn About Physical versus Chemical Properties so let's Jump right in and Take a
0:15Physical Properties it Says Right Here our Properties of Matter that described the Physical
0:21Characteristics of A substance and not how the Substance behaves Chemically Alright so Physical Properties will Tell you how that
0:28Substance behaves Physically but not Chemically for example if We said that aluminum Foil Is
0:34Malleable what does that mean what Does the word Malleable mean Where well it means?
0:39That the metal Is
0:42Has the Ability to be Hammered Into thin Sheets so we can?
0:45We Can Take Aluminium and Pound it down Into or Hammer it down Into thin Sheets so
0:50That's Not, Telling Us how this Aluminium Foil is going to react With something Else that's Just Telling Us how
0:55It'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
1:02That is the Ability of metal has to be turned Into wire for example if We Said Copper Is [matt] is Ductile?
1:10That Would be a Physical Property of that of that Copper that's not Telling us how
1:14It's going to Chemically react With something Else if We said The Boiling Point of Water Is a Hundred degrees Celsius
1:21Boiling Point Is a physical Property it doesn't tell Us how that that Water Is going to react or change
1:27Chemically Into Something Else it's Just Telling Us that at a Hundred degrees
1:31This This Liquid
1:33Substance Is going to turn Into
1:34Water Vapor Which Is a physical Change all right if We said the Frequency of this wave iS 20 Hertz
1:40Well then that Would Be a physical Property of This wave Frequency is the amount of Wavelengths that Pass A given Point Every Single
1:47Second so that [Would] be a physical Property [if] We talked about the Viscosity of Fluids how some Fluids are
1:55More Viscous Than Others for Example
1:58Honey Is more Viscous Than Water as a higher Viscosity that, would be A
2:04Physical Property of That and Last but not least Solubility
2:07We said Salt and Sugar Are Soluble in Water that Is Going to be A?
2:11Physical Property of Those Substances That Does not tell Us how the salt or sugar Is Going to behave
2:16Chemically
2:17[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
2:25Look Now at chemical Properties, okay
2:27Chemical Properties Are A little Different Chemical Properties [Or] [Properties] of a substance [that] describe how
2:32That Substance Is chemical Composition will Change given a Certain
2:37Specific Set of Conditions
2:39[Alright] so if We Take a look at A few examples of Chemical
2:42Properties if I said Gasoline is Flammable
2:44That Tells you how that Gasoline is going to react When Exposed to an Open Flame if We Said a substance, was?
2:50Radioactive That Tells you how the Nucleus of that atom is going to change
2:53Over Time if We said that something is corrosive Battery Acid is Corrosive?
2:58That Tells you how that acid Is Going to behave Chemically if We Said that [A] chemical
3:03Was A an Oxidizer which means that it has the Ability to Strip an Electron off Another Substance
3:10Well that Would be A chemical Property of that Substance right so things like Flammability
3:15Radioactivity
3:16A substance Being an Oxidizer or corrosive These are all chemical Properties if We Said That oxygen is Combustible?
3:24Once Again That tells Us how oxygen is going to react With an Open Flame
3:29Right it's going to be Converted Into Carbon Dioxide and Water Vapor if We said something is Toxic that too is A chemical Property?
3:36If We said tnt is explosive That too? Would be A?
3:39Chemical Property of That Substance and Last but not least if We Said that something is Pyrophoric that Means that that Substance
3:46Has the Ability to ignite When Exposed to air so that will be A chemical Property as
3:51Well so chemical Properties Are Properties of a substance [that] describe how that
3:55Substances Chemical Composition will Change given a specific set of
3:59Conditions 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
4:06All right Let's Take a look at this little List Here and Determine if They are Physical Or chemical
4:11Properties and I advise that You go Ahead and Pause this Video at this Point and Work Through These Yourself See if you Can Figure
4:17Out if These are Physical or chemical Properties so Freezing Point like
4:21We just got [then] Saying that's going to be a physical Property [of] Matter
4:25That's Not, Telling Us how, that's since Is going to change Chemically right if Something is Combustible
4:31Well that's going to be A chemical change right if We Said That oxygen Is?
4:36Combustible That Tells Us that oxygen
4:38Over Time is going to change the Carbon Dioxide and Water Vapor right if We Said that Sodium Metal Is
4:44Water reactive Which it is when you Throw it in Water There's A very violent Reaction it's A
4:50Chemical Change Has Taken place so that Water Reactivity, Would be A chemical Property of
4:57Say Sodium
4:59[Alright] if We said something as Viscous [that] Refers to?
5:03Fluids Ability to Flow so that's Going to be a physical Property
5:07If We said that [a] substance was Toxic that, also would be A I'm sorry that, Would be A chemical Property?
5:19A condensation Point right if We Said that Water Begins to Condense and Turn Back Into
5:25Our water [Vapour] condenses at 100 degrees Celsius and Turns Back Into Liquid that is going to be a physical Property
5:37This is [A] cool, Property all right Something is Pyrophoric that means it ignites an Air that's Going to be A chemical Property
5:48If Something is corrosive Like Battery Acid that's Going to be a chemical Property of That Substance and
5:54Last but not Least
5:56If We said that The melting Point of Ice is Zero degrees Celsius that [too] will be [a] physical [Property]?
6:03That's Not, Telling Us how
6:04That Ice is going to behave Chemically?
6:06All right so that is a Physical and Chemical Properties in A nutshell if You like what you see go Ahead and Click the little
