6 sample questions

Question 1.
What is viscosity?
Show hintHide hint
Think about how syrup flows compared to water.
Question 2.
How does temperature affect viscosity?
Show hintHide hint
Consider how heating syrup affects its flow.
3Question 3.
What happens to diffusion rates when viscosity increases?
- Increases
- Decreases
- Remains the same
Show hintHide hint
Remember the analogy of flowing syrup versus water.
4Question 4.
True or False: Convection decreases the resistance against mass transfer.
- True
- False
Show hintHide hint
Consider how stirring affects diffusion.
Question 5.
Consider two pollutants in a river: one with low viscosity and one with high viscosity. If both are subjected to the same temperature, which will diffuse faster and why?
Show hintHide hint
Refer to how syrup moves differently than water.
Question 6.
A scientist measures the diffusion rates of two gases in a controlled environment. Gas A has a molecular weight of 28 g/mol, while Gas B has 44 g/mol. Assuming temperature remains constant, compare their diffusion coefficients.
