Physical properties or physical property of a substance that can be measured or observed without any chemical change.
00:21
Physical property is the property that can be measured or observed without any chemical change.
00:52
While chemical property or chemical properties of any substance can be measured or observed when any substance undergo chemical change.
01:51
So in this question here we are given different properties and here we have to identify the physical and chemical properties.
02:00
So the first statement, this statement saying the melting point of iron is 1538.
02:15
Melting point of iron is 131538.
02:31
So as we know melting point and boiling point indicates or represent the physical properties because this can be observed without any chemical change.
02:48
So this is physical property of iron.
02:54
The second statement, this statement says solid iron can rust.
03:01
So here this is talking about rusting of iron.
03:14
And we know rusting of iron occurs when iron reacts with water in the presence of air.
03:28
So here we can see chemical reaction is taking place.
03:33
That's why this rusting of iron indicates chemical properties of iron.
03:46
And the third statement, this statement saying iron is shiny.
03:50
So here it is talking about shininess.
03:59
And as we know this shininess and colors and appearance indicate the physical property of any substance.
04:10
So shininess of iron is a physical property of iron.
04:21
In the next statement, this saying property, propane is combustile.
04:29
So propane is combustile that means it is talking about combusting or combustion reaction.
04:41
Combustion, combustion of propane.
04:49
And we know combustion process occurs when propane, combustion of propane occurs when propane reacts with oxygen.
05:02
So here a chemical reaction is taking place.
05:05
That's why this is a chemical property, chemical property of propane.
05:16
In the fifth statement, this is saying solid silver is tarnished.
05:22
So here this statement is talking about tarnishing of solid silver...
