To determine whether the student understands the basic differences between the solid, liquid and gaseous states in regard to the number and motion of molecules, distance between molecules, differences in volume and shape, and properties. 3. To learn the names and properties of common solids (example: most metals), liquids (example: water) and gases (example: air). Number of Participants: 1 Approximate Time: 30 minutes The Competition: 1. The contestants will classify pictures, models or real objects into one of these three categories. 2.

Solid Liquid Gas A liquid changes to a solid when the temperature rises (gets hotter) drops (gets colder) stays the same The point at which liquid water turns to water vapor (gas) is called the melting point vapor point boiling point freezing point The temperature at which a solid becomes a liquid is called its. melting point In order for a gas to change to a liquid by _condensation_, enough heat energy must be lost. Solids have a definite volume and shape. This means they cannot mold to the shape of a container. The change of a liquid to a gas is called evaporation. Heat Energy is a part of all state changes. Heating matter causes particles in a substance to move faster Solids contain small particles that are packed together in repeating order called Crystals.

The particles of a solid are closely packed together., Air is an example of a liquid. Condensation takes place when the particles of a gas lose enough thermal energy to form a liquid.

' b. flows quickly. c., flows slowly. d. fills its container. Fill in the blank to complete each statement. According to Charles,' s law, when the temperature of a gas increases in a flexible container, its ' increases. The faster gas particles are moving, the their energy and the temperature. At its, the particles of a solid are vibrating so fast that they break free from their fixed positions. occurs when the particles on the surface of a solid are directly released as a gas. When the temperature of a gas in a rigid container increases, its increases. True or False ' Bubbles of air exhaled by an underwater swimmer increase in volume as they rise to the water's surface. The volume of a gas is the result of gas particles pushing on the wails of the container. During boiling, only particles on the surface of the liquid gain enough energy to become gas. The change from a solid to a liquid is condensation.
16 Describe that matter is made up of tiny particles which cannot be seen with the naked eye. Identify the four phases of matter: solid, liquid, gas, and plasma. Describe solids as having definite shape and definite volume. Cite some examples of solids. Differentiate between crystalline solids and amorphous solids.

Define gases as matter with no definite shape and no definite volume. Describe a phase change as the process of matter changing from one phase another. Differentiate between melting, freezing, vaporization, and condensation. State the freezing point of water to be 0 Celsius. State the boiling point of water to be 100 Celsius. Describe the process of condensation and provide a common everyday example of condensation. Describe the difference between evaporation and vaporization. Solids, liquids, and gases are defined mainly by whether or not they hold their and. The particles in a solid move back and forth slightly but stay in their positions. Particles in a liquid are packed closely together but can and move past each other. Two characteristic properties of liquids are and
17 . The particles in a gas have energy of motion than the particles in a liquid or a solid. True or False A substance s state of matter is determined by the balance between the motions and attractive forces of its particles. When a substance loses thermal energy, the freedom of motion of its particles increases. The change from a gas to a liquid is called vaporization. The boiling and melting points of a substance depend on the pressure of the air above the substance. Vaporization and evaporation are opposite processes. Fill in the blank to complete each statement. When working with a gas, it is helpful to know three measurements:,, and. The pressure of a gas is the force of its outward push divided by. When the temperature of a gas increases at constant pressure, its volume. Charles s law shows that the volume of a gas is to its Kelvin temperature under constant pressure. Robert Boyle s experiments show that gas is inversely proportional to at constant temperature. Anything that has mass and takes up space is called a. a solution. b. an element. c. matter. d. thermal.
18 A pure substance made of two or more elements chemically combined in a set ratio is called a(n) a. atom. b. compound. c. solution. d. mixture. Every chemical or physical change in matter includes a change in a. state. b. energy. c. color. d. melting point. A change in state from solid to liquid is an example of a. a physical change. b. a chemical change. c. oxidation. d. electrolysis. Water has a distinct characteristic that sets it apart from other liquids on Earth. Water expands when it freezes. This means that solid ice is More dense than liquid water Less dense than liquid water Thicker than liquid water Thinner than liquid water The Particle Model of Matter helps to explain ideas about Thermal Energy. This model includes each of the following points EXCEPT... all substances are made up of tiny particles that are too small to see the particles are always in motion the particles increase their energy output when they collide the particles have spaces between them Another important idea about temperature and the particle theory is that the motion of particles increases when the temperature increases. Which statement below is correct? as the motion of particles decreases the temperature remains the same as the temperature decreases the motion of the particles also increases as the motion of the particles decreases the temperature decreases as the temperature increases the motion of the particles decreases The energy of movement is the kind of energy the particles of matter have.
