So now we're gonna take a look at the physical properties. Physical property itself is a measurable property that describes the state of a chemical compound. Here, it can be observed through your senses without changing the chemical structure of a substance, so it's something that we can observe by either seeing it, touching it, smelling it, using our own faculties. Now, some of the most common types of physical properties, if we take a look at these images, in the first one we have a color palette. So for my fellow artists, we're gonna say that color is a physical property; an object appears red, an object appears yellow. These colors that are shown to us represent physical properties. In the next image, we have a beaker filled with a liquid, which we can assume is water. Now one object sinks to the bottom of it while another one floats on top of it. Now what determines if an object is heavy enough to sink into the liquid or light enough to float on top is its density, so density is a physical property. Next, we have an image of an anvil, which is related to the idea of mass. So mass is a physical property. Next, we have a cube. The space inside the cube represents its volume. Next here, we have a pot which seems to be boiling or bubbling because the temperature has been raised on it. Here, we'd say that physical properties would be boiling point, but it wouldn't just stop at boiling point. We can also include here freezing point or melting point. Now boiling point we can abbreviate as bp, freezing point as fp, and melting point as mp. Finally, if we take a look at this last image, we have a diamond. So a diamond is known as one of the hardest natural materials in the universe. It's one of the hardest materials you can find in nature. So when we talk about a diamond, we're just talking about the hardness of an object. And also, besides hardness, we can talk about the opposite, the softness of a material. How easy is it for me to break that material versus how difficult it is? So we're talking about a scale of hardness to softness when we talk about a material. These here represent the most common types of physical properties you'll come across. And just remember, if you can observe an object with your senses, then that can represent a physical property. Now that we've gone over the basic idea of it, let's move on to the next video and let's tackle some questions where we have to either identify what is or isn't a physical property.

So if we take a look here at this example question, it says, which of the following represents a physical property? Now remember, a physical property can be observed through the use of our senses. If we look at option a, it says potassium metal is extremely reactive when placed in water. We're talking about the reactivity of potassium within water. Reactivity is a chemical property. Next, rusting is a common issue with aluminum. We've discussed before that rusting is how the surface of a metal interacts with oxygen in the air. It undergoes a chemical reaction, and since we're talking about rusting as a type of chemical reaction, this could represent a chemical property. Neon has an unreactive nature; whether something is reactive or non-reactive or unreactive, we're talking about its reactivity. So that is a chemical property. The butane in the lighter is highly flammable. Flammability is an example of a chemical property. Therefore, the answer here has to be option e. Here it says mercury is a silvery liquid at 25 degrees Celsius. We're talking about its appearance, its color. Color is one of the first physical properties we discussed, so e would have to be my answer. Remember, a chemical property has more to do with an object and how it undergoes a chemical reaction.
