QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Tyndall Effect and Brownian Movement.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A colloidal solution is kept undisturbed for a long time. Will the particles settle down? Explain your answer.
A mixture of water and fine clay shows a visible beam of light when a torch is shone through it. What phenomenon is being observed?
A student shines a laser pointer through a glass of water and observes no visible path of light. What does this indicate about the mixture?
Describe how the Tyndall effect can be demonstrated in a laboratory setting.
Describe the role of Brownian movement in the stability of colloidal solutions.
Explain how the Tyndall effect helps in the purification of water in water treatment plants.
Explain why Brownian movement becomes less significant as the size of colloidal particles increases.
Explain why the path of a beam of light becomes visible when it passes through a colloidal solution but not through a true solution.
Explain why the Tyndall effect is not observed in true solutions.
State one difference between the Tyndall effect and Brownian movement.
Which property of colloidal particles is responsible for the Tyndall effect?
