1. Which of the following represents a form of potential energy?

• A. A moving car
• B. A spinning top
• C. A raised hammer
• D. A rolling ball

Correct answer: c

Rationale: A raised hammer possesses potential energy due to its elevated position relative to the ground.

2. Which term describes the resistance of a substance to being hammered into different shapes?

• A. Viscosity
• B. Ductility
• C. Malleability
• D. Conductivity

Correct answer: c

Rationale: Malleability refers to the resistance of a substance to being hammered or pressed into different shapes without breaking.

3. Which of the following is NOT a type of epithelium

• A. Stratified squamous
• B. Simple cuboidal
• C. Stratified columnar
• D. Stratified columnar

Correct answer: D

Rationale: The correct answer is D, 'Stratified columnar.' Epithelial tissues are classified based on their structure and function. Stratified squamous epithelium consists of multiple layers of flattened cells and is found in areas that need protection, like the skin. Simple cuboidal epithelium is a single layer of cube-shaped cells that function in secretion and absorption, commonly found in kidney tubules. Stratified columnar epithelium is a rare type with multiple layers of column-shaped cells, primarily found in the male urethra. Since 'Stratified columnar' is a valid type of epithelium, it is NOT the correct answer for this question.

4. Which element is used in semiconductors like computer chips and solar panels?

• A. Germanium
• B. Silicon
• C. Gallium
• D. Arsenic

Correct answer: B

Rationale: Silicon's unique properties allow it to be manipulated to conduct or not conduct electricity, making it ideal for various electronic applications.

5. What property of a substance refers to its ability to undergo a chemical change and form new substances?

• A. Density
• B. Mass
• C. Reactivity
• D. Volume

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, forming new substances with different properties.

6. Which statement accurately describes the relationship between electron configuration and the periodic table?

• A. Elements within the same period have similar electron configurations.
• B. Elements within the same group have similar electron configurations in their outermost shell.
• C. Electron configuration has no influence on an element's position on the periodic table.
• D. The number of electron shells an element has determines its group on the periodic table.

Correct answer: B

Rationale: Elements within the same group have similar electron configurations in their outermost shell. This explains why elements in the same group often share similar chemical properties.
