The rate of diffusion is influenced by: THe size of the molecules in that larger diffuse more quickly The size in that smaller diffuse more quickly The color in that darker diffuse more slowly None of the above2. Which colour curve represents the lowest temperature Black Blue Red Purple3. Which statement is false Gases can be expanded without limit. The molecular weight of a gaseous compound is a non-variable quantity The density of a gas is constant as long as its temperature remains constant. (b) Pressure must be exerted on a sample of a gas in order to confine it.4. A gas sample is at STP. Which changes in temperature and pressure will cause this sample to behave more like an ideal gas? Increased temperature and increased pressure Decreased temperature and increased pressure Increased temperature and decreased pressure Decreased temperature and decreased pressure5. A real gas behaves least like an ideal gas under the conditions of High temperature and low pressure Low temperature and high pressure Low temperature and low pressure High temperature and high pressure6. In a real gas particles have complete inelastic collisions meaning no energy is lost. True False7. For a gas, which pair of variables are inversely proportional to each other (if all other conditions remain constant)? P, V V, T n, V P, T8. The following states how gases differ from solids except; They have collisions with close neighbors None of the above They have a higher amount of kinetic energy They can be compressed9. Each of the containers is shown at the same temperature. In which container is the average speed of the particles the fastest? Oxygen Hydrogen Chlorine Nitrogen10. According to the kinetic theory of gases, an ideal gas has all of the following characteristics but 1. Which one? Particles that mutually attract one another Particles whose size is nil or negligible Particles that are very far away from each other Particles that move randomly but in straight lines11. The rate of HCl vs NH4 is Faster Slower The same Equal12. A sample of oxygen occupies 47.2 liters under a pressure of 1240 torr at 25oC. What volume would it occupy at 25oC if the pressure were decreased to 730 torr? 29.3 L 47.8 L 80.2 L 32.3 L13. Kinetic-molecular theory is most useful and accurate when gases are at _____ or at _____ low temperature; high pressure high temperature; high pressure low temperature; low pressure high temperature; low pressure14. Which of the following statements is false? Molecules of CH4(g) at high pressures and low temperatures have no attractive forces between each other. Molecules of an ideal gas are assumed to have no significant volume. The properties of N2(g) will deviate more from ideality at -100oC than at 100oC. Van der Waal's equation corrects for the non-ideality of real gases.15. Which is an intermolecular force? Ionic bond Metallic bond Covalent bond Hydrogen bond16. A sample of nitrogen occupies 5.50 liters under a pressure of 900 torr at 25oC. At what temperature will it occupy 10.0 liters at the same pressure? 32°C -109°C 269°C 154°C17. The kinetic molecular theory assumes that the particles of an ideal gas Have collisions that result in the system losing energy Have strong attractive forces between them Are arranged in a regular geometric pattern Are in random, constant, straight-line motion18. Under which conditions of temperature and pressure does oxygen gas behave most like an ideal gas Low temperature and high pressure Low temperature and low pressure High temperature and low pressure High temperature and high pressure19. How do gas molecules move?: In a circular motion In curved-line paths In an orderly fashion Constantly and randomly20. Under which conditions of temperature and pressure does a sample of neon behave most like an ideal gas? 100 K and 0.25 atm 400 K and 0.25 atm 100 K and 25 atm 400 K and 25 atm21. Which gas sample at STP has the same total number of molecules as 2.0 liters of CO2 (g) at STP? 2.0 L of Cl2 (g) 6.0 L of He (g) 3.0 L of H2S (g) 5.0 L of CO2 (g)22. As the sealed, inflexible container is heated, the gas molecules inside Increase in volume Begin to move faster Condense to a liquide Become less dense23. According to the kinetic molecular theory, the particles of an ideal gas Are separated by great distances, compared to their size Have strong intermolecular forces Have no potential energy Are arranged in a regular, repeated geometric pattern24. The stopper is removed from the container of chlorine, at which temperature will the gas diffuse the fastest. 290 K 310 K 245 K 273 K25. According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas? The motion of the gas particles is random and straight-line. The separation between the gas particles is smaller than the size of the gas particles themselves. The collisions between the gas particles cannot result in a transfer of energy between the particles. The force of attraction between the gas particles is strong.26 out of 25Time is Up!
