State of Matter
The Three States of Matter
| Term | Definition |
|---|---|
| States of Matter | Solids, liquids and gases are different______ __ ______ that have different physical properties. |
| Solids | ______ are often hard. |
| Liquids | _______ fill containers. |
| Gases | ______ surround us in the air. |
| Phase | Solids , liquids and gases are states of matter, each of which are also known as a _____. |
| Compounds | Elements and _________ can move from one state to another, causing specific physical conditions change. |
| Physical Conditions | Matter, or elements and compounds, can change from one state to another when specific ________ __________ change. |
| Temperature | When the ___________ of a system goes up, the matter in the system becomes more excited and active. |
| Active State | If enough energy is pushed into a system, by a change such as an increase in temperature, a phase change may occur as the matter moves to a more ______ _____. |
| Molecule | If you give a liquid water ________ enough energy, it escapes the liquid phase and becomes a gas. The extra energy allows the molecules to change states. |
| Excited | When the temperature of the water goes up, the molecules get more _______ and bounce around a lot more. This extra energy can cause it to escape its liquid phase and become a gas. |
| Change States | Providing extra energy to an element or compound allows the molecules of that element of compound, to______ ______. |
| Steam | An example of matter changing states is when energy from a stove heats up liquid water and creates _____. |
| Physical | "Phase" describes the ________ state of matter. |
| Moves | Matter only _____ from one phase to another by physical means. |
| Energy | A physical change can be created by adding ______ (increasing the temperature) or by taking energy away (freezing something). |
| Pressure | In addition to adding or taking away energy, a physical change can be created by changing the ________ of a system. |
| Vacuum Chamber | If you place a glass of water in a ______ _______ and lower the pressure, you can begin to watch the water boil and the water molecules move to a gas phase. |
| Same Substance | When molecules move from one phase to another they are still the ____ _________. |
| Vapor | There is water _____ above a pot of boiling water. |
| Condense | Water vapor (or gas) can ________ and become a drop of liquid water in the cooler air. |
| Ice | If you put that liquid water or water drops in the freezer, it will become a solid piece of ___. |
| State | No matter what physical _____ H2O is in (solid, liquid, gas) it is always water. |
| Chemical Properties | Even though the physical states of an element or compound may change, such as a liquid to a gas or a solid to a liquid, the________ __________ remain the same. |
| Chemical Bonds | If a chemical change were to occur in water, it would build or break the ________ _____ in the water (H2O) molecules. |
| Atom | If you added or removed an ____ from a compound, such as H2O, a new compound would be formed. |
| Added | If you _____ a carbon (C) atom to a water compound (H2O) , you would create formaldehyde (H2CO). |
| Create | If you added an oxygen (O) atom to a water compound (H2O), you would ______ hydrogen peroxide (H2O2). |
| Chemical Change | When you add atoms to an existing compound to create a new compound, causing a ________ ______, the new compound that is created is not anything like the original compound. |
| Not | Changes in the physical state do ___ generally lead to any chemical change in compounds. |
