Welcome to your Kinetic Theory of Matter (STUDY BY TOPICS JUNIOR CLASS) NAME EMAIL PHONE NUMBER 1. Diffusion is the result of:Random motion of particlesAll of the mentionedConcentration gradientKinetic energy of particles2. What is the process by which heat is transferred from one place to another without use of a mediumradiationconductioncohesionconvection3. What type of motion is associated with the molecules of gas?Linear motionNewton’s law of motionConservative motionBrownian motion4. In steady state diffusion, which of the following remain unchanged with time?All of mentionedConcentration at sinkConcentration at sourceConcentration profile5. A person's mass is best measured inkilometresatomskilogramscelsius6. Since atoms can join together in many different waysmost matter is in the gaseous statethere are many different kinds of matterthere are few different kinds of mattermost matter is in the liquid state7. Liquid evaporates faster athigh pressuremedium pressureno pressurelow pressure8. In which state(s) of matter do the particles move least freely?Both solid and liquidGasLiquidSolid9. When matter changes from a liquid to a solid, itevaporatesmeltscondensesfreezes10. You want to demonstrate the phenomenon of diffusion to a group of school kids using two coloured gases. For this, you need to slow down the process. Which of the following tricks will help you achieve this feat?Cooling the gasesDecreasing the size of orificeUsing gases of larger molecular radiiAll of the mentioned11. Cooking gas containers are kept in a lorry moving with uniform speed. The temperature of the gas molecules inside will ________Remain the sameDecreases for some, while the increase for othersDecreaseIncrease12. On which factor does the average kinetic energy of gas molecules depend?MassNature of the gasVolumeTemperature13. Heat flow though states of matter by the following exceptconductioncohesionradiationconvection14. The rate of evaporation as temperature increasesincreasesremains normalthe samedecreases15. A characteristic of an object (matter) is called amassbehaviourstateparticleproperty16. Rate of evaporation is affected by the following excepttemperaturepressuresizesurface area17. Rate of solid-state diffusion does not depend on which of the following?GravityTemperatureDiffusing speciesHost solid18. When an automobile travels for a long distance, the pressure in the gas?Increases slightlyDecreases slightlyRemains the sameDecreases and then increases19. Which of the following is not true for steady-state diffusion?There is no net transfer of massThe concentration profile is linearThe diffusion flux is constantThe concentration gradient is constant20.
