Question 1 of 27070

Relative humidity is the percentage of water vapor that is in the air as compared to the maximum amount it can hold at __________.

🔍 Key Concepts

• Relative humidity definition in basic meteorology • Relationship between air temperature and how much water vapor air can hold • Difference between temperature and pressure when describing humidity

💭 Think About

• Ask yourself: when we say air is "full" of water vapor (100% humidity), what condition are we holding constant? • Which factor most strongly controls how much water vapor air can physically contain before condensation occurs? • Do pilots and mariners usually relate humidity limits to changes in temperature or to changes in barometric pressure?

✅ Before You Answer

• Make sure the option you choose refers to a single, specific condition, not something that is changing. • Check which variable is used on standard relative humidity charts (psychrometric charts). • Eliminate any options that are clearly unrelated to how much water vapor air can hold, such as irrelevant physical quantities.
