9 Language Arts Support LESSON 2 Word-Family Activity: Word Chart Different words can be categorized as different parts of speech. Nouns name people, places, things, or ideas. Verbs express action. Some verbs can be turned into nouns by adding the ending tion. Sometimes the final letter of the verb form of the word is dropped or changed or another letter is added before adding the tion ending. Verb translate converse expect Noun translation conversation expectation Directions: Complete the chart below with the correct word forms. Verb Noun vaporize condensation 3. sublime deposit 6. conserve evaporation attraction States of Matter

10 Language Arts Support LESSON 2 Word-Usage Activity: Building Adjectives with ed Endings An adjective is a word that modifies a noun or pronoun, and a verb expresses an action. Usually when you add ed at the end of a verb it changes the tense, but some verbs can be turned into adjectives by adding the ending. Verb increase absorb Adjective increased absorbed The recent heavy rain caused increased water levels in regional lakes. The absorbed dye colored the cloth bright blue. Directions: In each sentence below, circle the ed adjective and underline the noun that it describes. 1. Vaporized water is not visible, but it is in the air around us. 2. Greater kinetic energy results in an increased temperature. 3. In the morning, condensed water can be seen on leaves and grass. 4. The melted metal was poured into molds. 5. An evaporated liquid becomes a gas. 6. To become recycled aluminum, the metal must first be changed from a solid to a liquid and then changed back to a solid. 7.

16 Enrichment LESSON 2 Plasma The Fourth State of Matter What is the most common state of matter in the universe? You might be surprised to learn that it isn t a solid, a liquid, or a gas. It is a fourth state of matter known as plasma. Scientists estimate that plasma makes up as much as 99 percent of the visible universe. How does plasma form? After a liquid has changed to a gas, what happens if you keep adding energy? First, the molecules separate into gaseous atoms. At higher temperatures, electrons are stripped off the atoms. When you remove electrons from an atom, a positively charged particle called an ion remains. Therefore, the new substance, plasma, consists of a mixture of electrons and positively charged ions. or a plasma television. These devices use electricity, rather than heat, to strip electrons off atoms. The result is a mixture of a gas and a plasma, not a pure plasma. You might also see the effects of plasma in the aurora borealis, or Northern Lights. The colors result from plasmas in the upper atmosphere. Pure plasmas are the material of the stars, where temperatures can range from 10 million to 100 million degrees Kelvin. No material can hold matter at these temperatures. Stars such as our Sun have so much mass that gravity holds the plasma together. If scientists could re-create these temperatures on Earth, could they produce a plasma? Yes, but what would they keep it in? Unusual Properties Like a gas, plasma has no definite volume or shape. It is a fluid like liquids and gases. Plasma has some unique properties because it contains charged particles. It can carry an electrical charge and can be contained by electric or magnetic fields. Where do you find plasma? You can observe a partial plasma if you look at a fluorescent or neon light Applying Critical-Thinking Skills Directions: Answer each question. A Fifth State of Matter If plasma is produced by heating a gas to super-hot temperatures, what happens if you cool matter to a super-cold temperature? Scientists are working to find out. What they ve found so far suggests that, in a few years, we ll have to add a fifth state of matter. 1. Judge Why do science books tend to focus on three states of matter rather than four? 2. Infer The walls of fluorescent and neon lights are made of glass. Why is it possible for a solid such as glass to contain a plasma? 3. Hypothesize If scientists managed to produce a plasma on Earth, what might they keep it in? States of Matter 39

17 Challenge LESSON 2 Energy Changes in Water It takes a different amount of energy to raise the temperature of 1 g of water 1 C than it does to raise the temperature of 1 g of ice or steam 1 C. It also takes a different amount of energy to change 1 g of ice at 0 C to water at 0 C than it does to change 1 g of water at 100 C to steam at 100 C. The table shows the amount of energy needed to produce each of these changes. Energy Involved in Changes of State of Water Process Energy Required (in Joules) Raise temp. of 1 g of ice or steam 1 C. Raise temp. of 1 g of water 1 C. Change 1 g of ice (0 C) to water (0 C). Change 1 g of water (100 C) to steam (100 C) ,257 Analyze Data Use the data in the table above to answer the following questions. 1. How does the amount of energy needed to raise the temperature of 1 g of water 1 C compare to the energy needed to raise the temperature of 1 g of ice or steam 1 C? 2. About how much more energy does it take to change 1 g of water at 100 C to steam at 100 C than it takes to change 1 g of ice at 0 C to water at 0 C? 3. How much energy would you need to raise the temperature of 10 g of water 40 C? 4. You have 100 g of water at 50 C. How much energy would it take to change the water to steam at 100 C? 5. What change in energy is needed to change 1 g of steam at 100 C to ice at 0 C? 40 States of Matter

18 Skill Practice Form and Test a Hypothesis LESSON 2: 40 minutes How does dissolving substances in water change its freezing point? You know that when thermal energy is removed from a liquid, the particles move more slowly. At the freezing point, they move so slowly that the attractive forces pull them together to form a solid. What happens if the water contains particles of another substance, such as salt? You will form a hypothesis and test the hypothesis to find out. Materials 50-mL graduated cylinder triple-beam balance beaker styrene cup distilled water Also needed: balloons, ice, salt, test tubes, thermometers Learn It To form a hypothesis is to propose a possible explanation for an observation that is testable by a scientific investigation. You test the hypothesis by conducting a scientific investigation to see whether the hypothesis is supported. Try It 1. Read and complete a lab safety form. 2. Form a hypothesis that answers the question in the title of the lab. Record your hypothesis. 3. Use the data table to record your measurements. Water Salt water Time (min) Temperature ( C) Time (min) Temperature ( C) States of Matter 41

19 Skill Practice continued 4. Use a triple-beam balance to measure 5 g of table salt (NaCl). Dissolve the 5 g of table salt in 50 ml of distilled water. 5. Place 40 ml of distilled water in one large test tube. Place 40 ml of the salt-water mixture in a second large test tube. 6. Measure and record the temperature of the liquids in each test tube. 7. Place both test tubes into a large foam cup filled with crushed ice-salt slush. Gently rotate the thermometers in the test tubes. Record the temperature in each test tube every minute until the temperature remains the same for several minutes. Apply It 8. How does the data tell you when the freezing point of the liquid has been reached? 9. Was your hypothesis supported? Why, or why not? 10. Key Concept Explain your observations in terms of how temperature affects particle motion and how a liquid changes to a solid. 42 States of Matter
