CHANGING STATES OF MATTER

1. and compounds can move from one toanother and not change. The water is made up of twohydrogen (H) atoms andor:e oxygen (0) atom. Ithas the same molecularstructure whether it is a , , or .Although its physical state may change, its remainsthe same.

2. If the formula of water were to change, that would be a

STATES OF MATTER

1. There are five main of matter. Each ofthese _is also known as a . The phase or state of matter can changewhen the temperature changes. Generally, as the temperature --:-----:_-,-matter moves to a more state. Phase describes a physical stateof matter. The key word to notice is . Things only move fromone phase to another by physical means.

2. If energy is (like increasing the temperature or increasingpressure) or if energy is (like freezing something ordecreasing pressure) you have created a physical change.

CHANGING ST.I\TES OF MATTER

1. matter can move from one state to another. It may require verylow or very pressures, but it can be done. Phasechanges happen when certain are reached. Sometimes aliquid wants to become a solid. Scientists use something called a_______________ to measure when that liquid turns into a solid.

2. Draw a picture that involves a solid changing to a liquid with an energyflow.

3. You're a cube of ice sitting on a counter. You dream of becoming liquidwater. You need some . Atoms in a liquid have .,...-energy than the atoms in a solid. The easiest energy around is probably________ . There is a magic temperature for every substance called the___________ . When a solid reaches the temperature of its melting point itcan become a . For water, the temperature has to be a littleover zero degrees . If you were salt, sugar, or wood yourmelting point would be than water.

4. The reverse is true if you are a gas. You need to lose some ----:-:-- _from your very excited gas atoms. The easy answer is to lower thesurrounding . When the temperature drops, energy will be_______ of your gas atoms. When you reach the temperature of thecondensation point, you become a . If you were the steam of aboiling pot of water and you hit the wall, the wall would be so _that you would quickly become a. _

CHEMICAL VS. PHYSICAL CHANGES

1. Physical changes are about and ~.Chemical changes happen on a level.

2. When you step on a can and crush it, you have forced a________________ . The shape of the object has changed. It wasn't achange in the , but something changed. When you melt anice cube you have also forced a (adding energy). Thatexample caused a change in the . You can causephysical changes with forces like motion, , and pressure.

3. Chemical changes happen on a much scale. While someexperiments show obvious changes such as a color change,most chemical changes happen between molecules and are .When iron (Fe) rusts you can see it happen over a long period oftime. Theactual molecules have changed their (the iron oxidized).Melting a sugar cube is a change because the substance isstill sugar. Burning a sugar cube is a change. The_____________ ofthe fire has broken down the bonds.

4. changes can happen over a series of steps, and the resultmight have the same number of atoms but have a different ~

EVAPORATION OF LIOUIDS

1. Sometimes a liquid can be sitting in one place (maybe a puddle) and itsmolecules will become a . That's the process called____________ . It can happen when liquids are or when they are_________ . It happens often with liquids.Evaporation is all about the in individual molecules, not aboutthe average energy of a system.

2. It turns out that all can evaporate at __temperature and air pressure. Evaporation happenswhen atoms or molecules from the liquid and turn into a

3. The energy you can measure with a thermometer is really an____________ of all the molecules in the system. There are always a fewmolecules with a lot of energy and some with barely any energy at all. Themolecules with a lot of energy are able to build up enough to
