| Question | Answer |
|---|---|
| 3. Use condensation nucleus in a separate sentence | Condensation nucleus is a solid particle in the atmosphere that provides the surface on which water vapor condenses |
| 10. When the temperature of the air decreases, the rate of evaporation | |
| 13. Cloud form when the water vapor in air condenses as | |
| 14. The prefix nimbo- and the suffix - nimbus mean | |
| 21. Explain how a psychrometer measures humidity | |
| 23. Describe how precipitation is measured | |
| 26. Where would air contain more water vapor: over Panama or over Antarctica? Explain your answer | |
| 27. One body of air has a relative humidity of 97%. Another has a relative humidity of 44%. At the same temperature, which body of air is closer to its dew point? Explain your answer | |
| 30. How would a significant decrease in condensation nuclei in the world's atmosphere affect cloud formation and climate | |
| 33. At 15* C, air reaches saturation when it contains 10g of water vapor per 1 kg of air. What is the relative humidity of air at 15* C if the air contains 7g of water vapor per 1 kg of air | |
| 36. Estimate the relative humidity at 6:00 a.m. | |
| 37. Estimate the temperature at 6:00 a.m. | |
| 38. Explain why relative humidity might be the highest at 6:00 a.m. | |
| 39. When is relative humidity the lowest | |
| 40. How does humidity vary relative to temperature? | |
| D. Decreases | |
| C. Snow falls | |
| C. Rain | |
| Relative humidity can be measured by an instrument called a hygrometer. | |
| The rain gauge is a meteorological instrument for measuring the amount of precipitation fallen during a given time interval at a certain location | |
| Panama: The warmer the air the greater the amount of water vapor it contain. When warm damp air cools it drops the water as it just can't hold it anymore | |
| The closer air is to its dew point the higher the relative humidity will be. At the dew point the relative humidity will be 100% | |
| Water vapor condenses best when particles allow it to form up, a little like how you need a seed to grow crystals | |
| The realitive humidity would be 2 | |
| 30 degrees Celsius | |
| 10 degrees Celsius | |
| The temperature dose not change and relative humidity is a measure of how close the air is to reaching the dew point | |
| Relative humidity is then at its lowest during mid day when it is the hottest outside | |
| Specific humidity dose not change with ambient air temperature, but Relative humidity dose decrease with increasing ambient air temperature |
