Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is flux in the context of environmental science?

💡 Hint: Think of it as the amount of a chemical moving across a boundary over time.

Question 2

Easy

Define the partition constant.

💡 Hint: It's a balance reference between two states.

Question 1

What does 'flux' refer to in environmental science?

  • A measure of temperature variation
  • The flow of a substance across a surface
  • The amount of moisture in the air

💡 Hint: Consider the movement of air or fluids.

Question 2

True or False: The partition constant does not change with moisture content.

  • True
  • False

💡 Hint: Reflect on how moisture levels can alter chemical distribution.

Challenge Problems

Push your limits with challenges.

Question 1

In a lab experiment measuring dibenzofuran flux, the soil's moisture is 20%, and the partition constant is adjusted. If the moisture drops to 10%, calculate the expected change in flux assuming a linear relationship.

💡 Hint: Consider how the partition constant effects scaling with moisture.

Question 2

A researcher measures airflow velocity at two heights above the ground. If at height 1 (z1), the velocity is 2 m/s and at height 2 (z2), it is 4 m/s, calculate the friction velocity (v*) assuming no other forces are acting.

💡 Hint: Remember to refer to tje equation concerning surfaces for better accuracy.
