Show Answer Key & Explanations
Step-by-step solution for: matter and energy review worksheet
Explanation:
Let’s go step by step through each section.
Section 1: Fill in the blanks using the word list
Word list: Gas, Plasma, Physical, Solid, Energy, Liquid, Matter, Chemical, Evaporation
1. “______ is anything that has mass and volume”
→ That’s the definition of Matter. ✔
2. “The two states of matter that occupy a definite volume are ______ & ______”
→ Solids have definite shape *and* volume; liquids have definite volume but not shape. Gases and plasma do *not* have definite volume. So: Solid & Liquid ✔
3. “______ & ______ are the other two states of matter”
→ We already used Solid and Liquid. The remaining common states are Gas and Plasma (plasma is the 4th state, often included at this level). ✔
4. “______ changes alter the identity of a substance”
→ When identity changes (e.g., iron → rust), it’s a Chemical change. ✔
5. “______ changes do not alter the identity of a substance”
→ Like ice melting → water — still H₂O. That’s a Physical change. ✔
Section 2: Identify PC (Physical Change) or CC (Chemical Change)
Remember:
- Physical change = same substance, just looks different (state, shape, phase)
- Chemical change = new substances formed (color change, gas, rust, burning, etc.)
1. Water boiling → liquid to gas (H₂O still H₂O) → PC
2. Butter melting → solid to liquid (still butter) → PC
3. Wood rotting → decomposition by microbes → new substances → CC
4. Glass breaking → shape changes, still glass → PC
5. Magnetizing a nail → aligns domains, no new substance → PC
6. Iron rusting → Fe → Fe₂O₃ (rust), new substance → CC
7. Alcohol evaporating → liquid to gas, still alcohol → PC
8. Leaves changing color → chlorophyll breaks down, new pigments form → CC
9. Mowing the lawn → cutting grass, still grass → PC
10. Baking a cake → ingredients react (e.g., baking soda + acid → CO₂), irreversible, new substances → CC
Section 3: Fill in blanks with second word list
Words: Elements, Symbols, Properties, Letters, Pure, Periodic table, Carbon Dioxide, Compound
1. “______ cannot be separated by physical or chemical means”
→ Elements are pure substances made of one type of atom; you can’t break them down further chemically. ✔
2. “Elements are abbreviated with ______, which consist of one or two ______”
→ Elements use Symbols, made of one or two Letters (e.g., O, Na) ✔
3. “Elements are organized on the ______”
→ Periodic table ✔
4. “Two or more elements chemically combined make up a ______”
→ That’s a Compound ✔
5. “Carbon is an example of an element and ______ is an example of a compound”
→ Carbon Dioxide (CO₂) is a compound ✔
6. “Elements and compounds are called ______ substances because they have a unique set of chemical and physical ______”
→ They are Pure substances, with unique Properties ✔
Now let’s compile all answers clearly.
Final Answer:
1. Matter
2. Solid & Liquid
3. Gas & Plasma
4. Chemical
5. Physical
1. PC
2. PC
3. CC
4. PC
5. PC
6. CC
7. PC
8. CC
9. PC
10. CC
1. Elements
2. Symbols, Letters
3. Periodic table
4. Compound
5. Carbon Dioxide
6. Pure, Properties
