Write your answer on your notebook. Across: 4. It is an element that doesn’t have the characteristics of metal. 5. It is an element that having the nature of metal. 9. A place that is disorderly or objectionable place. 10. A _ is something that causes the deterioration or eating away of metal. Down: 1. A is something, such as a pipe or tunnel, through which water or electrical wires or other designated items can pass. 2. ___ means a hollow cylinder. 3. Poly vinyl Chloride. 6. It is something that bends easily, is easily persuaded or can be changed easily. 7. Hard metal, not flexible. 8. Something that has the consistency of water
The Correct Answer and Explanation is:
Here are the correct answers for the crossword puzzle, along with a detailed explanation:
Answers:
Across:
4. Nonmetal – An element lacking metallic characteristics.
5. Metal – An element that possesses metallic properties.
9. Slum – A disorderly, poorly maintained place.
10. Corrosive – A substance that causes metal to deteriorate or erode.
Down:
- Conduit – A channel for water, wires, or other substances.
- Tube – A hollow cylinder used to transport fluids or gases.
- PVC – Abbreviation for Poly Vinyl Chloride, a common plastic material.
- Flexible – Easily bent or modified; adaptable.
- Rigid – A hard, stiff material that does not bend easily.
- Liquid – A substance that flows and takes the shape of its container.
Explanation (Approx. 300 words):
The crossword puzzle tests the understanding of both general scientific and material-related vocabulary. Starting with Across, number 4 refers to an element without the physical or chemical features of metals such as conductivity or malleability. The correct term is nonmetal. Number 5 seeks the opposite, simply metal, which denotes elements like iron or copper known for conducting heat and electricity. Number 9 describes a poor or neglected area, often overcrowded, which is aptly called a slum. Number 10 asks for a substance that deteriorates metal, which is corrosive—often acids or salts that lead to rusting or pitting.
In the Down clues, number 1 describes a passage used in infrastructure or electronics—called a conduit. This term applies to both physical water pipes and electrical wire channels. Number 2 refers to a tube, a fundamental shape in engineering used to carry substances. Number 3 provides a chemical abbreviation: PVC, which stands for Poly Vinyl Chloride, a durable plastic used in plumbing and electrical insulation.
Number 6 calls for a term describing an object that bends or changes shape easily—flexible. Number 7 contrasts that with rigid, which indicates stiffness and resistance to bending. Finally, number 8 defines a substance with a water-like consistency, best matched by liquid, a fundamental state of matter.
Each of these terms contributes to foundational knowledge in material science, chemistry, and basic engineering.
