Diffusion in Solids Liquids and Gases
Chemistry ⇒ States of Matter
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 12
A student observes that the smell of ammonia reaches him faster than the smell of chlorine gas. Explain why.
A student places a drop of blue ink in a beaker of water and observes the color spreading throughout the water over time. What process is being observed?
Describe how the diffusion of gases is utilized in the process of respiration in plants.
Describe how the diffusion of potassium permanganate in water demonstrates diffusion in liquids.
Describe the effect of increasing temperature on the rate of diffusion in gases.
Explain why diffusion is a spontaneous process.
A student observes that the smell of ammonia reaches him faster than the smell of chlorine gas. Explain why.
A student places a drop of blue ink in a beaker of water and observes the color spreading throughout the water over time. What process is being observed?
Diffusion occurs fastest in which state of matter? (1) Solid (2) Liquid (3) Gas (4) Plasma
Which factor does NOT affect the rate of diffusion? (1) Temperature (2) Concentration gradient (3) Color of the substance (4) Particle size
Which of the following best describes the difference between diffusion and osmosis? (1) Diffusion involves only gases, osmosis involves only liquids. (2) Diffusion is the movement of any particles, osmosis is the movement of water across a semipermeable membrane. (3) Diffusion requires energy, osmosis does not. (4) Diffusion occurs only in solids, osmosis occurs only in gases.
Which of the following best explains why gases diffuse faster than liquids? (1) Gases have higher density (2) Gases have more intermolecular forces (3) Gases have more kinetic energy and larger spaces between particles (4) Gases are heavier than liquids
Diffusion in solids is generally ________ compared to liquids and gases.
Diffusion in solids is often observed over a period of ________.

The movement of dye molecules from an area of high concentration to low concentration in water is an example of ________.
True or False: Diffusion can occur against a concentration gradient without energy input.
True or False: Diffusion can occur in solids, liquids, and gases.
True or False: Diffusion in gases is independent of pressure.
True or False: Diffusion is a physical process and does not involve any chemical change.
