Diffusion in Solids Liquids and Gases starts at 8 and continues till grade 12.
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.
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)?
The movement of bromine vapor from one end of a glass tube to the other is an example of _______.
