Rate of solid-state diffusion does not depend on which of the following? Host solid Temperature Gravity Diffusing species 2. Osmosis is different from diffusion as: Osmosis requires a liquid solvent Osmosis is a form of active transport Diffusion requires semi-permeable membrane In osmosis, solute moves from lower concentration to higher 3. When an automobile travels for a long distance, the pressure in the gas? Increases slightly Remains the same Decreases slightly Decreases and then increases 4. Heat flow though states of matter by the following except cohesion radiation convection conduction 5. A person's mass is best measured in kilometres atoms celsius kilograms 6. Which of the following is not true for steady-state diffusion? The concentration gradient is constant There is no net transfer of mass The diffusion flux is constant The concentration profile is linear 7. Rate of evaporation is affected by the following except size pressure surface area temperature 8. The rate of evaporation as temperature increases the same increases decreases remains normal 9. The quantity of matter in an object is known as mass height volume size 10. Cooking gas containers are kept in a lorry moving with uniform speed. The temperature of the gas molecules inside will ________ Decrease Increase Decreases for some, while the increase for others Remain the same 11. In which state(s) of matter do the particles move most freely? solid Liquid Gas Both liquid and gas 12. A characteristic of an object (matter) is called a behaviour particle mass property state 13. When matter changes from a liquid to a solid, it evaporates condenses freezes melts 14. 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? Decreasing the size of orifice Cooling the gases All of the mentioned Using gases of larger molecular radii 15. The change from a liquid to a gas is called condensation evaporation melting freezing 16. What type of motion is associated with the molecules of gas? Brownian motion Conservative motion Linear motion Newton’s law of motion 17. Everything that takes up space and has mass is liquid solid gas matter 18. On which factor does the average kinetic energy of gas molecules depend? Mass Temperature Volume Nature of the gas 19. In steady state diffusion, which of the following remain unchanged with time? Concentration at source Concentration at sink Concentration profile All of mentioned 20. Liquid evaporates faster at low pressure medium pressure high pressure no pressure 1 out of 20 Time is Up!
