Welcome to your Kinetic Theory of Matter (STUDY BY TOPICS JUNIOR CLASS) NAME EMAIL PHONE NUMBER 1. In which state(s) of matter do the particles move most freely? Both liquid and gas Liquid solid Gas2. A characteristic of an object (matter) is called a behaviour mass state property particle3. The quantity of matter in an object is known as height volume size mass4. Which state of matter has negligible cohension force fluid liquid gaseous solid5. What is the boiling point of water 0 degree Celsius 100 degree Celsius 50 degree Celsius 90 degree Celsius6. All matter is made of tiny particles called elements mass atoms properties7. Everything that takes up space and has mass is matter solid gas liquid8. The rate of evaporation as temperature increases remains normal the same decreases increases9. In steady state diffusion, which of the following remain unchanged with time? Concentration at source Concentration profile Concentration at sink All of mentioned10. 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? All of the mentioned Decreasing the size of orifice Using gases of larger molecular radii Cooling the gases11. The change from a liquid to a gas is called melting evaporation condensation freezing12. Liquid evaporates faster at no pressure high pressure low pressure medium pressure13. On which factor does the average kinetic energy of gas molecules depend? Mass Volume Temperature Nature of the gas14. Rate of evaporation is affected by the following except pressure surface area size temperature15. Heat flow though states of matter by the following except conduction radiation convection cohesion16. What type of motion is associated with the molecules of gas? Newton’s law of motion Conservative motion Linear motion Brownian motion17. When matter changes from a liquid to a solid, it condenses melts freezes evaporates18. Diffusion is the result of: Kinetic energy of particles All of the mentioned Random motion of particles Concentration gradient19. Diffusion is not used in which of the following? Doping of semiconductors Catalysis Manufacturing of alloys Heat treatment of metals20. In which state(s) of matter do the particles move least freely? Liquid Both solid and liquid Gas Solid21 out of 20Time is Up!
