16.2.7. Surface Area

Try these first

1. 1.

   What is evaporation?

   Hint

   Think about what happens when water heats up.

2. 2.

   What does a larger surface area do to evaporation?

   Hint

   Remember more area means more water exposed.

3. 3.

   Does larger surface area lead to higher evaporation rates?

   • True
   • False

   Hint

   Remember our discussion of EASE.

4. 4.

   The process of water changing from liquid to vapor is called what?

   Hint

   What happens when water gets hot?

5. 5.

   Calculate the difference in evaporation loss between a small pond (3 m²) and a large lake (150 m²) over a hot day with similar temperatures. Assume evaporation rates of 5 mm/day per m².

   Hint

   Use the evaporation formula and consider the area!

6. 6.

   Design a water usage plan for a farm with a 200 m² irrigation pond. Calculate potential evaporation loss over 10 days with a rate of 7 mm/day.

   Hint

   Focus on how often and much water is likely to evaporate based on surface area.
