What is the boiling point of water 90 degree Celsius 50 degree Celsius 0 degree Celsius 100 degree Celsius 2. The rate of evaporation as temperature increases increases remains normal the same decreases 3. When matter changes from a liquid to a solid, it evaporates melts condenses freezes 4. Since atoms can join together in many different ways there are many different kinds of matter there are few different kinds of matter most matter is in the liquid state most matter is in the gaseous state 5. In which state(s) of matter do the particles move least freely? Liquid Solid Gas Both solid and liquid 6. Everything that takes up space and has mass is liquid matter gas solid 7. The change from a liquid to a gas is called melting evaporation condensation freezing 8. Diffusion is the result of: All of the mentioned Kinetic energy of particles Concentration gradient Random motion of particles 9. All matter is made of tiny particles called elements properties atoms mass 10. What is the process by which heat is transferred from one place to another without use of a medium cohesion convection radiation conduction 11. Rate of evaporation is affected by the following except size temperature pressure surface area 12. Which of the following is not true for steady-state diffusion? The diffusion flux is constant The concentration gradient is constant The concentration profile is linear There is no net transfer of mass 13. A person's mass is best measured in celsius atoms kilograms kilometres 14. Which state of matter has negligible cohension force liquid fluid solid gaseous 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 remains the same Pressure may increase or decrease Pressure will decrease 16. 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 Remain the same Increase 17. Rate of solid-state diffusion does not depend on which of the following? Host solid Temperature Gravity Diffusing species 18. Diffusion is not used in which of the following? Doping of semiconductors Manufacturing of alloys Catalysis Heat treatment of metals 19. When an automobile travels for a long distance, the pressure in the gas? Decreases slightly Remains the same Increases slightly Decreases and then increases 20. Liquid evaporates faster at low pressure no pressure medium pressure high pressure 1 out of 20 Time is Up!
