Particulate Nature of Matter 1. Which statement is INCORRECT about Liquid particles? Cohesive forces between particles in Liquid are weaker compared to those in solid. Due to weak cohesive forces they can flow and take shape of a container Cohesive forces between Liquid particles are Stronger compared to those in Solid. When a Liquid is heated it changes into Gaseous state. Question 1 of 24 2. If you cut paper into small pieces endlessly until it cannot be cut into pieces or subdivided anymore, you are: Trying to demonstrate that matter is made up of tiny particles. Trying to demonstrate that matter is not made up of tiny particles. Trying to demonstrate that matter is made up of solid, gas and liquids. None of the above Question 2 of 24 3. Which of the following is NOT an experiment to demonstrate that matter is made up of tiny particles? Dilution of potassium permanganate crystals in water.Cutting a piece of paper into many tiny particles Dissolving salt in water Brownian Motion in Liquids Question 3 of 24 4. What is the difference in the diffusion process when you pour some Copper (ii) sulphate solution into cold water and some from the same sample in warm water? Diffusion of copper sulphate will be faster in warm water than in cold waterNo difference at all Diffusion of copper sulphate will be slower in warm water than in cold waterDiffusion of copper sulphate will not occur in cold water but only in warm water.Question 4 of 24 5. As a student in the Lab, explain why you can detect a Gas Leakage? It is possible to detect because of diffusion of the Gas from the Leak pointDue to the color visible of the Gas from the Leak point Due to the smell of the Gas from the Leak point None of the above Question 5 of 24 6. Brownian Motion suggests that particles of Liquids i.e. water or air is in constant random movement. True False Maybe None Question 6 of 24 7. What does a smoke cell experiment investigate? Diffusion in Liquids Brownian motion in air Confirming the suggestion that air is made up of small particles which are in constant motion diffusion in solidsQuestion 7 of 24 8. Matter is anything that occupies space and has Mass True False Maybe None Question 8 of 24 9. Which of the following states of matter has the fastest rate of diffusion? Solid state Gas state Liquid state moltenQuestion 9 of 24 10. State how a decrease in temperature will affect Brownian motion? It will result to an increase in the constant random motion of particlesNo effect at all It will result to a decrease in the constant random motion of particlesNone of the above Question 10 of 24 11. Condensation is a process where gas molecules lose some of their energy and fall back into Liquid state. TRUEFalse Maybe None Question 11 of 24 12. State how an increase in temperature will affect Brownian motion? It will result to an increase in the constant random motion of particlesIt will result to a decrease in the constant random motion of particlesIt will have no affect at all None of the above Question 12 of 24 13. What results to different gasses having different rates of diffusion? Gases have different densities Denser gases have heavier particles while less dense gases have lighter particles.A denser gas moves more slowly than a lighter one.All of above Question 13 of 24 14. Which statement is INCORRECT about particles in SOLID state of Matter? Solid particles have a strong force of attraction between particles of the same kind Increasing the temperature increases the rate of vibration of solid particles to and fro. At a certain temperature for a particular solid, the particles breakaway from the solid structure and the solid melts. Decrease of temperature for a particular solid will increase the rate of vibration Question 14 of 24 15. Vaporization is the process when a liquid is heated and changes to gaseous state. True False Maybe None Question 15 of 24 16. Which statement is INCORRECT about Gas particles? Gas particles have an increased random motion compared to Liquid particlesCohesive forces between gases is extremely small compared to Liquid particles Gas particles when compared in a container they collide with each other resulting to Gas pressure. Gas particles can be heated up to be changed into solid state. Question 16 of 24 17. When you pour Copper (ii) sulphate solution in water which principle are you trying to investigate? Diffusion in Liquids Diffusion in solids Diffusion in gases None of the above Question 17 of 24 18. Why is Diffusion in Gases faster than in Solids or Liquids? Low density High kinetic energy Low cohesive forces All of above Question 18 of 24 19. Which of the following particles has the highest random motion? Solid particles Liquid particlesGas particles None Question 19 of 24 20. Which of the following is NOT a state of matter? Solid Gas Liquid Vacuum Question 20 of 24 21. Define Kinetic Theory of matter Matter is made up of very small particles which are immobile Matter is made up of very small particles which are in constant random motion Matter is made up of very BIG particles which are in constant random motion. Matter is made up of particles which IN MOTION. Question 21 of 24 22. Diffusion is the process by which particles spread from regions of high concentration to those of low concentration? True False Maybe None Question 22 of 24 23. Why is the Diffusion of copper sulphate faster in warm water than in cold water? Because movement of particles is faster in hot liquids due to increased energy Because of a decrease in the kinetic energy of the particle with decrease in temperature. temperature does not change anythingNone of above Question 23 of 24 24. Sublimation is the process by which a solid changes directly to gaseous state when heated Maybe False True None Question 24 of 24 Loading...
