OBJECTIVE ASSESSMENT
GUIDE



2024

,1. What is the primary mechanism by which thermal energy is conducted in
metals?

a. Phonon scattering

b. Electron mobility

c. Vacancy diffusion

d. Freezing transitions

Answer: b. Electron mobility

Rationale: Metals have free electrons that facilitate rapid thermal
conductivity.



2. In a solar cell, which material property is most critical for efficient energy
conversion?

a. Thermal conductivity

b. Electrical resistivity

c. Band gap

d. Density

Answer: c. Band gap

Rationale: The band gap determines the energy range in which the cell
can absorb and convert solar energy into electricity.



3. Which law best explains the relationship between pressure and volume
in a closed system of gas at constant temperature?

a. Charles's Law

b. Avogadro's Law

, c. Boyle's Law

d. Pascal's Law

Answer: c. Boyle's Law

Rationale: Boyle's Law states that for a fixed amount of gas at constant
temperature, pressure and volume are inversely proportional.



4. In a double-slit interference experiment, what causes the dark fringes
observed on the screen?

a. Constructive interference

b. Destructive interference

c. Diffraction of light

d. Reflection of light

Answer: b. Destructive interference

Rationale: Dark fringes occur due to the destructive interference of
light waves, where path differences result in phase cancellations.



5. What is the primary function of leukocytes in the human body?

a. Oxygen transport

b. Blood clotting

c. Nutrient transport

d. Immune response

Answer: d. Immune response
