Which of the following is not true for steady-state diffusion?The concentration profile is linearThe diffusion flux is constantThe concentration gradient is constantThere is no net transfer of mass2. The quantity of matter in an object is known assizevolumeheightmass3. The change from a liquid to a gas is calledevaporationmeltingcondensationfreezing4. Which state of matter has negligible cohension forcefluidgaseoussolidliquid5. In which state(s) of matter do the particles move most freely?LiquidGassolidBoth liquid and gas6. When matter changes from a liquid to a solid, itfreezescondensesmeltsevaporates7. Diffusion is the result of:Kinetic energy of particlesConcentration gradientAll of the mentionedRandom motion of particles8. Osmosis is different from diffusion as:Diffusion requires semi-permeable membraneOsmosis is a form of active transportOsmosis requires a liquid solventIn osmosis, solute moves from lower concentration to higher9. Air in a cylinder is suddenly compressed by a piston which is then maintained at the same position. After sometime, the ________Pressure may increase or decreasePressure will increasePressure remains the samePressure will decrease10. A person's mass is best measured incelsiuskilogramskilometresatoms11. Since atoms can join together in many different waysthere are few different kinds of matterthere are many different kinds of mattermost matter is in the gaseous statemost matter is in the liquid state12. What is the boiling point of water 100 degree Celsius90 degree Celsius50 degree Celsius0 degree Celsius13. What type of motion is associated with the molecules of gas?Brownian motionLinear motionConservative motionNewton’s law of motion14. When an automobile travels for a long distance, the pressure in the gas?Decreases and then increasesDecreases slightlyIncreases slightlyRemains the same15. All matter is made of tiny particles calledmasselementspropertiesatoms16. Diffusion is not used in which of the following?Heat treatment of metalsDoping of semiconductorsManufacturing of alloysCatalysis17. 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 othersIncreaseDecrease18. In steady state diffusion, which of the following remain unchanged with time?All of mentionedConcentration at sourceConcentration profileConcentration at sink19. Liquid evaporates faster atmedium pressureno pressurehigh pressurelow pressure20. 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 radiiCooling the gasesDecreasing the size of orificeAll of the mentioned21 out of 20Time is Up!
