Key Concepts

Physical Properties

Physical properties are characteristics of a substance that can be observed or measured without changing its chemical identity. These include traits like color, density, melting point, boiling point, and state of matter. They provide information about the physical nature of a material and can often be determined through direct observation or simple measurements.

Chemical Properties

Chemical properties describe a substance's ability to undergo chemical changes that transform it into different substances. These properties, such as flammability, reactivity, acidity, and oxidation states, are observed during a chemical reaction. They indicate how a substance interacts with other chemicals and what kind of chemical transformations it may experience under various conditions.

0:00 Hi.

00:02 So this question is asking you to explain the difference between physical and chemical property using examples.

00:08 So first let's go over what a physical property is.

00:11 A physical property is a property that can only be observed during physical changes.

00:16 And physical changes, you can determine that depending on if the substance involved changes its identity or chemical composition.

00:23 So let me show you an example to make that a little more clear.

00:26 Here we have an ice cube, which is solid water, right? and then i add some heat to it.

00:32 And of course, that ice cube melts and becomes liquid water.

00:36 So is this a physical change? or has the identity of the substance changed from when i added the heat? no, right? the identity of the substance is still the same.

00:48 It is still water.

00:49 It's still h2o.

00:50 It might have changed physical state, but the identity and chemical composition of the substance itself has not changed.

00:57 So this is a physical change, and therefore we are exploring a physical change.

01:00 Physical property.

01:02 And the physical property we are exploring is the melting point or the temperature at which a particular substance will convert from solid to liquid.

01:13 Now let's look at chemical properties.

01:16 So chemical properties are the exact opposite...
