🔍 Key Concepts

• Meaning of the prefix "hygro-" in scientific terms • How some cargoes interact with moisture/humidity in the air • Differences between absorbing moisture vs releasing moisture

💭 Think About

• Think about where you may have seen the word part "hygro" before (for example, in weather instruments) and what it measures. • Ask yourself whether a hygroscopic cargo is more of a concern in humid conditions or dry conditions, and why. • Consider whether the key behavior of this cargo relates to water as a liquid or water as vapor/gas in the air.

✅ Before You Answer

• Identify what "hygro" refers to in meteorology or physics (e.g., humidity, moisture). • Determine whether the cargo’s main property is to absorb moisture or emit/give off moisture. • Check whether the description should involve water in vapor (gas) form rather than in liquid form.
