When we talk about matter, we can look at it in two main ways: through physical properties and chemical properties. Let’s go over the important differences between these two types.

Physical Properties

These are things we can see or measure without changing what the substance is. Here are some examples:

• Color: This is what we see, like how water is clear.
• Melting and Boiling Points: These are the temperatures when a substance changes from solid to liquid (like ice melts at 0°C) or from liquid to gas (like water boils at 100°C).
• Density: This tells us how heavy something is for its size. For example, a piece of metal feels heavier than a piece of wood that is the same size.

Chemical Properties

On the other hand, chemical properties tell us how a substance can change into something new. Here are some examples:

• Reactivity with Acids: For example, when metals mix with hydrochloric acid, they can create hydrogen gas.
• Flammability: This means that some things, like gasoline, can catch fire and change into different substances when they burn.

Summary

In short, remember that physical properties are things we can see without changing the substance. Chemical properties are about how substances can change into something new. Understanding these ideas can help you know more about matter!
