Sample Module 2 Physics Practice Questions

Try these sample questions to review concepts for the Module 2 Physics exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which state of matter is characterized by having a definite volume but no fixed shape, conforming to the shape of its container while maintaining a constant surface level?
A.Solid
B.Liquid
C.Gas
D.Plasma
Explanation: A liquid has a fixed (definite) volume because its molecules are held close together by strong attractive intermolecular forces, but it lacks a fixed shape because the molecules can slide past one another. Solids have both definite shape and volume; gases and plasmas have neither.
2In atomic physics, the mass number (nucleon number, A) of an atom is defined as the total number of:
A.Protons only
B.Protons and neutrons
C.Electrons and protons
D.Neutrons and electrons
Explanation: The mass number (A) of an atom is the sum of the number of protons and neutrons located within its nucleus. The atomic number (Z) represents the number of protons alone, which equals the number of orbital electrons in a neutral atom.
3Which of the following best describes an aircraft structural alloy such as 2024-T3 aluminium?
A.A pure chemical element
B.A metallic mixture of elements tailored for specific mechanical properties
C.A chemical compound with fixed stoichiometric ratio
D.An ionic crystal lattice of metallic salts
Explanation: An alloy is a solid solution or mixture of two or more elements (with at least one being a metal). 2024-T3 aluminium is predominantly aluminium alloyed with copper, magnesium, and manganese to enhance yield strength, toughness, and fatigue resistance.
4An aircraft fuel tank contains 250 litres of AVGAS with a density of 0.72 kg/L. What is the mass of the fuel contained in the tank?
A.150 kg
B.180 kg
C.200 kg
D.225 kg
Explanation: Mass is calculated using the density formula m = ρ × V. Given density ρ = 0.72 kg/L and volume V = 250 L: m = 0.72 kg/L × 250 L = 180 kg.
5A hydraulic fluid sample has a specific gravity (relative density) of 0.88 at 15°C. What is the mass of 0.05 m³ of this fluid? (Density of water = 1000 kg/m³)
A.35.2 kg
B.44.0 kg
C.50.0 kg
D.88.0 kg
Explanation: Specific gravity (SG) is the ratio of fluid density to water density. Thus, ρ_fluid = 0.88 × 1000 kg/m³ = 880 kg/m³. Mass m = ρ × V = 880 kg/m³ × 0.05 m³ = 44.0 kg.
6The attractive force between molecules of DIFFERENT substances, such as liquid sealant adhering to an aluminium aircraft panel, is defined as:
A.Cohesion
B.Adhesion
C.Surface tension
D.Viscosity
Explanation: Adhesion is the intermolecular attraction between unlike molecules (e.g., sealant and metal). Cohesion is the attraction between like molecules of the same substance.
7How does an increase in temperature typically affect the surface tension of a liquid fuel?
A.Surface tension increases due to higher molecular kinetic energy
B.Surface tension decreases because increased thermal agitation weakens intermolecular cohesive forces
C.Surface tension remains completely constant regardless of temperature
D.Surface tension fluctuates randomly with pressure changes
Explanation: As liquid temperature increases, molecular kinetic energy increases, weakening cohesive intermolecular forces at the surface. Consequently, surface tension decreases continuously as temperature rises toward the critical point.
8A solid titanium fitting has a mass of 2.25 kg and displaces a volume of 0.0005 m³ (500 cm³). What is the density of the titanium alloy?
A.2250 kg/m³
B.4500 kg/m³
C.7850 kg/m³
D.9000 kg/m³
Explanation: Density ρ = m / V. Given mass m = 2.25 kg and volume V = 0.0005 m³: ρ = 2.25 / 0.0005 = 4500 kg/m³.
9A technician mixes 4.0 litres of Fluid A (specific gravity 0.80) with 6.0 litres of Fluid B (specific gravity 1.10). Assuming no volume contraction, what is the specific gravity of the resulting mixture?
A.0.92
B.0.95
C.0.98
D.1.02
Explanation: Total mixture volume V_total = 4.0 + 6.0 = 10.0 L. Mass equivalent A = 4.0 L × 0.80 = 3.20 kg-eq. Mass equivalent B = 6.0 L × 1.10 = 6.60 kg-eq. Total mass equivalent = 3.20 + 6.60 = 9.80 kg-eq. Specific gravity of mixture SG_mix = 9.80 kg-eq / 10.0 L = 0.98.
10Which type of chemical bonding involves a 'sea' of delocalized valence electrons shared among positive metal ions, conferring high electrical and thermal conductivity to aircraft structural metals?
A.Ionic bonding
B.Metallic bonding
C.Covalent bonding
D.Hydrogen bonding
Explanation: Metallic bonding consists of positive metal ions held together by a surrounding sea of delocalized electrons that move freely, giving metals high electrical/thermal conductivity and ductility.
