Q

What does a hygrometer measure?

🔍 Key Concepts

• Difference between humidity and temperature • Instruments used for measuring weather conditions on board (barometer, anemometer, thermometer, hygrometer) • Meaning of the prefix "hygro-" in scientific terms

💭 Think About

• Think about what the ship’s barometer is already used for—would a hygrometer duplicate that job or measure something different? • Recall common bridge or weather instruments: which one is used when you are concerned about moisture in the air, like fog or dew? • Break down the word: what does "hygro" typically relate to in science—heat, pressure, moisture, or wind?

✅ Before You Answer

• Identify which option relates specifically to moisture in the air rather than heat, pressure, or motion. • Eliminate the option that is clearly measured by a barometer and the one measured by an anemometer. • Confirm that the remaining choice is about water vapor or moisture content in the atmosphere.
