Welcome to your Kinetic Theory of Matter (STUDY BY TOPICS JUNIOR CLASS) NAME EMAIL PHONE NUMBER 1. The rate of evaporation as temperature increasesincreasesthe sameremains normaldecreases2. A person's mass is best measured incelsiusatomskilometreskilograms3. Rate of evaporation is affected by the following excepttemperaturesurface areapressuresize4. The quantity of matter in an object is known asheightmassvolumesize5. Since atoms can join together in many different waysmost matter is in the gaseous statethere are few different kinds of matterthere are many different kinds of mattermost matter is in the liquid state6. On which factor does the average kinetic energy of gas molecules depend?TemperatureNature of the gasMassVolume7. What type of motion is associated with the molecules of gas?Linear motionConservative motionBrownian motionNewton’s law of motion8. Rate of solid-state diffusion does not depend on which of the following?Host solidDiffusing speciesGravityTemperature9. In which state(s) of matter do the particles move least freely?LiquidSolidGasBoth solid and liquid10. Which state of matter has negligible cohension forcegaseousliquidsolidfluid11. In steady state diffusion, which of the following remain unchanged with time?Concentration at sinkConcentration profileConcentration at sourceAll of mentioned12. When an automobile travels for a long distance, the pressure in the gas?Decreases and then increasesIncreases slightlyDecreases slightlyRemains the same13. Which of the following is not true for steady-state diffusion?The concentration gradient is constantThere is no net transfer of massThe concentration profile is linearThe diffusion flux is constant14. Diffusion is not used in which of the following?CatalysisDoping of semiconductorsHeat treatment of metalsManufacturing of alloys15. All matter is made of tiny particles calledmasspropertieselementsatoms16. The change from a liquid to a gas is calledevaporationmeltingfreezingcondensation17. When matter changes from a liquid to a solid, itfreezescondensesevaporatesmelts18. 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?Using gases of larger molecular radiiDecreasing the size of orificeAll of the mentionedCooling the gases19.
