Question 1

What does the vapor pressure deficit measure?

  • The difference between actual and saturation vapor pressures
  • Only the actual vapor pressure
  • Wind speed

💡 Hint: Recall that it is about two types of vapor pressures.

Question 2

Dalton's Method is sensitive to measurement errors.

  • True
  • False

💡 Hint: Think about the importance of accurate measurements in scientific methods.

Challenge Problems

Push your limits with challenges.

Question 1

A research team measures the saturation vapor pressure at a lake to be 2.2 kPa and the actual vapor pressure to be 0.9 kPa. If the wind speed is 5 m/s and they have found an empirical constant 'C' of 0.9, calculate the evaporation rate.

💡 Hint: Plug in the values carefully to find the evaporation rate.

Question 2

Consider a scenario where rainfall reduces the actual vapor pressure significantly. How does this impact the evaporation calculation using Dalton’s Method?

💡 Hint: Think about how humidity and moisture levels directly affect evaporation.
