1In marine heat calculations, sensible heat is best defined as the heat that:
A.Causes a change of phase at constant temperature
B.Raises or lowers the temperature of a substance without a phase change
C.Is always equal to the product of mass and latent heat of vaporisation
D.Is lost only by radiation from hot surfaces
Explanation: Sensible heat changes temperature without changing phase (Q = mcΔT). Latent heat is absorbed or released at constant temperature during a phase change.
2How much heat is required to raise the temperature of 20 kg of steel (c = 0.48 kJ/kg·K) from 25 °C to 75 °C?
A.240 kJ
B.480 kJ
C.960 kJ
D.1 200 kJ
Explanation: Q = mcΔT = 20 × 0.48 × (75 − 25) = 20 × 0.48 × 50 = 480 kJ.
3Latent heat of vaporisation is the heat required to:
A.Raise liquid temperature by 1 °C at constant pressure
B.Change unit mass of liquid completely into vapour at constant temperature
C.Raise solid temperature by 1 °C at constant volume
D.Increase the pressure of a gas at constant temperature
Explanation: Latent heat of vaporisation is heat per unit mass to change liquid to vapour (or reverse) at constant temperature during boiling/condensation.
4How much heat is absorbed when 5 kg of water at 100 °C is completely vaporised? (h_fg ≈ 2 257 kJ/kg)
A.1 128.5 kJ
B.4 514 kJ
C.11 285 kJ
D.22 570 kJ
Explanation: Q = m × h_fg = 5 × 2 257 = 11 285 kJ. Temperature stays at 100 °C during boiling at standard pressure.
5Enthalpy of a fluid stream is most usefully thought of as:
A.Internal energy only, ignoring flow work
B.Internal energy plus the flow work term (u + pv), often used in open-system heat balances
C.Kinetic energy of the fluid only
D.Latent heat of fusion only
Explanation: Specific enthalpy h = u + pv. In marine plant heat balances (boilers, condensers, refrigeration), enthalpy differences give heat transfer rates for flowing fluids.
6Which mode of heat transfer requires no intervening material medium?
A.Conduction
B.Convection
C.Radiation
D.Forced convection only
Explanation: Thermal radiation transfers energy by electromagnetic waves and can occur through a vacuum. Conduction and convection need matter.
7Jacket cooling water removing heat from a diesel cylinder liner is primarily an example of:
A.Radiation through a vacuum
B.Conduction only with no fluid motion
C.Convection (fluid carrying heat away)
D.Nuclear heat generation
Explanation: Cooling water absorbs heat at the liner and carries it away — forced convection. Conduction occurs through the metal wall, but the fluid stream removes heat by convection.
8A steel rod 2.0 m long has a linear expansivity α = 12 × 10⁻⁶ /K. How much does it expand when heated through 80 K?
A.0.96 mm
B.1.92 mm
C.3.84 mm
D.19.2 mm
Explanation: ΔL = L₀ α ΔT = 2.0 × 12×10⁻⁶ × 80 = 1.92 × 10⁻³ m = 1.92 mm.
9If the coefficient of linear expansion of a metal is α, the coefficient of cubical (volumetric) expansion is approximately:
A.α/3
B.α
C.
D.
Explanation: For isotropic materials, γ ≈ 3α. Area expansion is ≈ 2α.
10A copper pipe (α = 17 × 10⁻⁶ /K) is 30 m long at 15 °C. What is its free expansion if heated to 65 °C?
A.12.75 mm
B.25.5 mm
C.51 mm
D.8.5 mm
Explanation: ΔT = 50 K. ΔL = 30 × 17×10⁻⁶ × 50 = 0.0255 m = 25.5 mm.

About the MCA General Engineering Science II Exam

MCA General Engineering Science II is the IAMI written academic module covering Applied Heat plus Electrotechnology and Naval Architecture for restricted management-level engineer Certificate of Competency pathways (including small vessel and yacht engineer routes). Per MIN 565 (M), from December 2019 the paper is sectioned: candidates must achieve at least 40% in each section and at least 50% overall. The official GOV.UK syllabus tests heat energy and expansion, gas laws, combustion and engine powers, basic refrigeration, Ohm’s law and circuit power, resistance temperature effects, secondary cells, electromagnetic induction, electrical instruments, hydrostatic thrust and Archimedes, and box-shape transverse stability including GM = (m × d) / Δ. DISCLOSURE: The official assessment is a written paper. This free bank is an English-language multiple-choice study adaptation of that syllabus — not an official IAMI/SQA paper.

Assessment

Official GES II (from December 2019 per MIN 565): two scoring sections — (1) Applied Heat and (2) Electrotechnology and Naval Architecture. Candidates must score at least 40% in each section and at least 50% overall. The GOV.UK syllabus covers heat engines (heat energy, gas laws, combustion, refrigeration), electro-technology (circuits, resistance, secondary cells, induction, instruments), and naval architecture (fluids at rest; box-shape transverse stability). This practice set converts that assessable knowledge into four-option MCQs for study fluency.

MCA General Engineering Science II Study Tips from Top Performers

1Drill sectional pass awareness: you need ≥40% in Applied Heat AND ≥40% in Electrotechnology & Naval Architecture plus ≥50% overall — do not ignore a weak section hoping overall marks will carry you
2Memorise heat relationships: Q = mcΔT for sensible heat and Q = mL for latent heat; keep SI units consistent (kg, J/kg·K, °C or K for temperature difference)
3Practise Boyle (PV = C at constant T), Charles (V/T = C at constant P) and the combined gas law PV/T = C with absolute temperatures in kelvin
4For combustion, separate stoichiometric air by mass from excess air; know why excess air is needed in real IC engines and boilers
5Engine powers: IP from MEP × L × A × N (and number of cylinders/cycles), BP from brake, mechanical efficiency = BP/IP, thermal efficiency from heat in fuel
6Electrical drills: series R total = sum; parallel 1/R = sum of reciprocals; P = VI = I²R = V²/R; watch unit prefixes (mA, kΩ, kW)
7Secondary cells: charge/discharge chemistry of lead-acid, capacity in ampere-hours, and series vs parallel effects on voltage and capacity
8Naval architecture: hydrostatic force = ρgAh for horizontal surfaces; for box ships practise KG/KB/KM relationships and GM = (m × d) / Δ for transverse shifts
9Work timed calculation sets under exam conditions — the real paper is written calculation, not multiple choice

Frequently Asked Questions

What is MCA General Engineering Science II?

GES II is the IAMI written academic examination covering Applied Heat together with Electrotechnology and Naval Architecture. It supports MCA restricted management-level engineer CoC pathways such as small vessel and yacht engineer routes.
