Problem Analysis:
The worksheet is about identifying whether certain objects are
matter or
not matter and understanding the properties of matter. Let's break it down step by step.
#### Part A: Identify Whether the Object is Matter or Not Matter
We need to determine if each item listed is
matter (M) or
not matter (NM). Matter is defined as anything that has mass and occupies space. Non-matter includes things like energy, emotions, or abstract concepts.
1.
Brick: A brick is a solid object made of clay or other materials. It has mass and occupies space.
-
Answer: M
2.
Helium (in a balloon): Helium is a gas, which is a form of matter. It has mass and occupies space.
-
Answer: M
3.
Fruit juice: Fruit juice is a liquid, which is a form of matter. It has mass and occupies space.
-
Answer: M
4.
Shadow: A shadow is not matter; it is the absence of light caused by an object blocking light. It does not have mass or occupy space.
-
Answer: NM
5.
Salt: Salt is a solid substance composed of sodium and chloride ions. It has mass and occupies space.
-
Answer: M
6.
Happiness: Happiness is an emotion, which is not matter. It is an abstract concept and does not have mass or occupy space.
-
Answer: NM
7.
Coffee: Coffee is a liquid, which is a form of matter. It has mass and occupies space.
-
Answer: M
8.
Noise: Noise is a form of sound, which is a type of energy. It does not have mass or occupy space.
-
Answer: NM
9.
Ice popsicle: An ice popsicle is a solid object made of frozen liquid (usually water with flavoring). It has mass and occupies space.
-
Answer: M
10.
Steam: Steam is water vapor, which is a gas. It has mass and occupies space.
-
Answer: M
11.
Light: Light is a form of electromagnetic radiation, which is energy. It does not have mass or occupy space.
-
Answer: NM
12.
Heat: Heat is a form of thermal energy, which is not matter. It is the transfer of energy and does not have mass or occupy space.
-
Answer: NM
#### Part B: Fill in the Blanks
The question asks what all matter has. The two key properties of matter are:
1.
Mass: All matter has mass.
2.
Volume: All matter takes up space (volume).
So, the answers should be:
- All matter have (1)
mass and take up (2)
space.
Final Answer:
#### Part A:
1. M
2. M
3. M
4. NM
5. M
6. NM
7. M
8. NM
9. M
10. M
11. NM
12. NM
#### Part B:
All matter have (1)
mass and take up (2)
space.
Final Answer Boxed:
\[
\boxed{\text{M, M, M, NM, M, NM, M, NM, M, M, NM, NM}}
\]
\[
\boxed{\text{mass, space}}
\]
