- Let's start with the 3 states of matter, Solid, Liquid, Gas.
- The stages of matter are classified according to physical and chemical properties.
- Namaste everyone,my friend tom here will explain us all the types of matter and be together with us in this journey.
- Zdrs: 2
- Hello there Jimmy! How does it feel being a solid?
- Hey Tim! It feels nice being a solid. Did you know that when you're a solid the molecules are very close together and barely move.
- The states of matter have to do with how the molecules interact with each other. The molecules in the solids are very closely packed together.This means that the bonds of the molecules are still connected.
- Zdrs: 3
- Hey Tom. As you can see the house was at a warm temperature so i melted into a liquid.
- Jimmy? You aren't solid ice anymore. How is that possible?
- Now my molecules are moving around a little bit. My molecules are interacting with each other but their bonds aren't connected.
- Solid was turned into liquid because the warm temperature melted the solid ice. It increased the energy which now caused the molecules to separate from the bonds and move around. Liquid has an indefinite shape.
- Zdrs: 4
- Well, Tom I evaporated into steam. It's the last state of matter, remember.
- What!? Jimmy now you're steam. How?
- The liquid evaporates into vapor or steam known as a Gas. The energy is greater in a gas because the molecules are freely moving around fast. Gas has an indefinite shape and volume.
- Zdrs: 5
- Chemical Properties
- Now let's learn about two properties of matter.
- Some of the chemical properties are reactivity, flammability.
- Flammability
- Chemical properties are a material characteristic changes into one or more new substances. Matter changes chemical properties when two different substances interact with each other.
- Zdrs: 6
- Physical Properties
- The second property of matter is Physical properties.
- Some of the physical properties are color, odor, density.
- Ice turning into water
- Color
- Physical properties are any materials characteristics without the identity of the substance changing. For example, a leaf changing colors in the fall. The leaf stays the same just the color changes.
