1. What is the relationship between temperature and evaporation?

　　a) Inverse

　　b) Direct

　　c) No relationship

　　d) Random

　　答案：b) Direct

　　解析：The higher the temperature, the faster the molecules move, increasing the chances of evaporation.

　　填空题

2. Complete the sentence: "the higher the temperature is, __________ the liquid evaporates."

　　答案：the faster

　　解析：Higher temperature causes molecules to move faster, leading to increased evaporation.

　　判断题

3. True or False: Lower temperature accelerates evaporation.

　　答案：False

　　解析：Lower temperature reduces molecular movement, slowing down the evaporation process.

　　论述题

4. Explain the relationship between temperature and evaporation using scientific principles.

　　答案：Evaporation is the process by which molecules in a liquid state gain enough energy to enter the gaseous state. Higher temperatures provide more kinetic energy to the molecules, causing them to move faster and eventually transition into the gas phase. As a result, higher temperatures lead to increased evaporation rates.

5. How does humidity affect the rate of evaporation?

　　答案：High humidity slows down the evaporation process because the air already contains a high moisture content, making it more difficult for additional moisture to evaporate from the liquid surface. Conversely, low humidity facilitates faster evaporation as the dry air can effectively absorb the evaporated moisture.

　　Overall, the rate of evaporation is significantly influenced by both temperature and humidity, with higher temperatures and lower humidity levels accelerating the process.
