Which is the term used to describe the energy required to increase the surface area of a liquid?ViscosityDepositionSurface tensionSurfactant4. The kinetic molecular theory assumes that the particles of an ideal gasHave strong attractive forces between themAre arranged in a regular geometric patternHave collisions that result in the system losing energyAre in random, constant, straight-line motion5. Which is defined as the combination of pressure and temperature at which all three states of matter can coexist at equilibrium?Triple pointDeposition pointMelting pointCritical point6. What total gas volume (in liters) at 520oC and 880 torr would result from the decomposition of 33 g of potassium bicarbonate according to the equation:2KHCO3(s) K2CO3(s) + CO2(g) + H2O(g)19 L10 L37 L56 L7. For a gas, which pair of variables are inversely proportional to each other (if all other conditions remain constant)?P, Tn, VV, TP, V8. According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas?The separation between the gas particles is smaller than the size of the gas particles themselves.The force of attraction between the gas particles is strong.The collisions between the gas particles cannot result in a transfer of energy between the particles.The motion of the gas particles is random and straight-line.9. According to the kinetic theory of gases, an ideal gas has all of the following characteristics but 1. Which one?Particles that are very far away from each otherParticles that mutually attract one anotherParticles that move randomly but in straight linesParticles whose size is nil or negligible10. Under which conditions of temperature and pressure does a sample of neon behave most like an ideal gas?400 K and 0.25 atm400 K and 25 atm100 K and 0.25 atm100 K and 25 atm11. Which postulate of the KMT explains why gases do not have a fixed volume.The particles of gas do not exert any force of attraction or repulsion on each other. There is no energy loss during a collision.The particles of gas are in constant motion and move in straight lines.The mean kinetic energy of the particles is directly proportional to their absolute temperature.All particles are infinitely small and the size of a particle is negligible compared to the container that it holds.12. The ideal gas law predicts that the molar volume (volume of one mole) of gas equals:RT/P1/2ms-²(MW)P/RTgRT/PV13. The concept of an ideal gas is used to explain Why some gases are monatomicWhy some gases are diatomicThe behavior of a gas sampleThe mass of a gas sample14. Which colour curve represents the lowest temperatureBlackPurpleBlueRed15. How do gas molecules move?:In an orderly fashionIn a circular motionConstantly and randomlyIn curved-line paths16.

Which of the following changes requires an input of thermal energy?EvaporationDepositionFreezingCondensation18. The following states how gases differ from solids except;They have a higher amount of kinetic energyThey have collisions with close neighborsThey can be compressedNone of the above19. 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 pressureDecreased temperature and increased pressureIncreased temperature and decreased pressureDecreased temperature and decreased pressure20. Each of the containers is shown at the same temperature. In which container is the average speed of the particles the fastest?HydrogenNitrogenOxygenChlorine21. In a real gas particles have complete inelastic collisions meaning no energy is lost. FalseTrue22. As the sealed, inflexible container is heated, the gas molecules insideIncrease in volumeCondense to a liquideBegin to move fasterBecome less dense23. Which is the state change that occurs when a solid becomes a gas without becoming a liquid first?VaporizationSublimationDepositionFreezing24. The rate of diffusion is influenced by: The color in that darker diffuse more slowlyNone of the aboveThe size in that smaller diffuse more quicklyTHe size of the molecules in that larger diffuse more quickly25.
