Which of the following statements about the density of water is true? What does humidity measure? What phenomenon do tornadoes typically form under?
Understand the Problem
The questions are asking about the properties of water and weather phenomena, specifically the density of water, what humidity measures, and the conditions under which tornadoes typically form.
Answer
3. D), 4. D), 5. D)
- D) The density of water decreases at higher temperatures.
- D) The amount of water vapor compared to its maximum capacity.
- D) Severe thunderstorms.
Answer for screen readers
- D) The density of water decreases at higher temperatures.
- D) The amount of water vapor compared to its maximum capacity.
- D) Severe thunderstorms.
More Information
Water's density decreases with temperature increase due to expansion. Humidity measures water vapor's relative amount to saturation point. Tornadoes form in severe thunderstorms, linked with extreme weather patterns.
Tips
A common mistake is confusing water density with volume or temperature. Humidity is often incorrectly thought of in terms of temperature rather than vapor saturation.
