🔍 Key Concepts

• Cargo sweat vs. ship sweat – understand the difference and where condensation forms • Meaning of dew point and how it relates to condensation on colder surfaces • How non‑ventilated holds affect temperature and moisture around cased machinery

💭 Think About

• Ask yourself: For condensation to form on the cargo, what must be true about the temperature of the cargo compared to the surrounding moist air? • Which option describes a situation where moist air meets a colder surface and water droplets form directly on that surface? • In a non‑ventilated hold, which condition would most likely cause water droplets to form on the machinery cases themselves rather than on the ship’s structure?

✅ Before You Answer

• Be clear on the definition: dew point is the temperature at which air becomes saturated and condensation begins • Decide whether the question is about cargo sweat (on the cargo) or ship sweat (on the ship’s structure) • Check which answer choice links dew point (moisture in the air) to a surface that is colder than that dew point
