QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Diffusion in Solids Liquids and Gases.
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 9
Describe how diffusion is important in biological systems.
Describe what happens when a drop of ink is placed in a beaker of still water.
Explain why a solid like copper sulfate can diffuse into water, but much more slowly than a gas.
Explain why diffusion is important for the survival of living organisms.
Explain why diffusion occurs faster in gases than in liquids.
Explain why the rate of diffusion decreases as the size of the diffusing particles increases.
Explain why the smell of ammonia spreads quickly in a room.
If the molar mass of gas A is 4 g/mol and gas B is 16 g/mol, what is the ratio of their rates of diffusion (rate of A : rate of B)?
In which state of matter are the particles most free to move and thus diffuse the fastest?
State Graham’s law of diffusion.
State one difference between diffusion in liquids and diffusion in gases.
State one everyday example of diffusion in gases.
When a crystal of potassium permanganate is placed at the bottom of a beaker of water, the color spreads upwards. What does this demonstrate about the movement of water molecules?
Why does diffusion occur more slowly in liquids than in gases?
Why does increasing the concentration gradient increase the rate of diffusion?
