Welcome to your Kinetic Theory of Matter (STUDY BY TOPICS JUNIOR CLASS) NAME EMAIL PHONE NUMBER 1. Osmosis is different from diffusion as: Osmosis requires a liquid solvent Osmosis is a form of active transport In osmosis, solute moves from lower concentration to higher Diffusion requires semi-permeable membrane 2. 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 3. Rate of solid-state diffusion does not depend on which of the following? Temperature Host solid Gravity Diffusing species 4. A person's mass is best measured in kilometres kilograms atoms celsius 5. What is the process by which heat is transferred from one place to another without use of a medium convection radiation conduction cohesion 6. Everything that takes up space and has mass is gas liquid solid matter 7. Cooking gas containers are kept in a lorry moving with uniform speed. The temperature of the gas molecules inside will ________ Decrease Decreases for some, while the increase for others Increase Remain the same 8. The change from a liquid to a gas is called evaporation melting condensation freezing 9. What is the boiling point of water 100 degree Celsius 90 degree Celsius 50 degree Celsius 0 degree Celsius 10. Diffusion is the result of: Concentration gradient All of the mentioned Random motion of particles Kinetic energy of particles 11. Heat flow though states of matter by the following except cohesion convection radiation conduction 12. In steady state diffusion, which of the following remain unchanged with time? Concentration at sink Concentration at source Concentration profile All of mentioned 13. On which factor does the average kinetic energy of gas molecules depend? Nature of the gas Temperature Volume Mass 14. A characteristic of an object (matter) is called a behaviour property state mass particle 15. Air in a cylinder is suddenly compressed by a piston which is then maintained at the same position. After sometime, the ________ Pressure will increase Pressure will decrease Pressure remains the same Pressure may increase or decrease 16. Since atoms can join together in many different ways most matter is in the gaseous state there are many different kinds of matter most matter is in the liquid state there are few different kinds of matter 17. The quantity of matter in an object is known as volume size mass height 18. Which state of matter has negligible cohension force solid gaseous fluid liquid 19. Which state of matter has the highest kinetic force gaseous solid fluid liquid 20. Rate of evaporation is affected by the following except surface area temperature size pressure 1 out of 20 Time is Up! Time's up
