Welcome to your Kinetic Molecular Model of Matter and Temperature(Senior Class Physics Study by Topics) NAME EMAIL PHONE NUMBER 1. According to the kinetic theory of gases, an ideal gas has all of the following characteristics but 1. Which one?Particles whose size is nil or negligibleParticles that move randomly but in straight linesParticles that mutually attract one anotherParticles that are very far away from each other2. Gases are similar to liquids in that;They are both considered fluidsThey take the shape of their containerThey cannot be compressedThey have a definite volume3. The kinetic molecular theory assumes that the particles of an ideal gas Have strong attractive forces between themAre in random, constant, straight-line motionAre arranged in a regular geometric patternHave collisions that result in the system losing energy4. Which state of matter exhibits only vibrational movement?GasPlasmaSolidLiquid5. The ideal gas law predicts that the molar volume (volume of one mole) of gas equals:gRT/PVRT/P(MW)P/RT1/2ms-²6. Which postulate of KMT explains why gases are so easily compressed?3- The particles of gas do not exert any force of attraction or repulsion on each other. There is no energy loss during a collision.4- The mean kinetic energy of the particles is directly proportional to their absolute temperature.2- The particles of gas are in constant motion and move in straight lines.1‐ All particles are infinitely small and the size of a particle is negligible compared to the container that it holds.7.

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.All particles are infinitely small and the size of a particle is negligible compared to the container that it holds.The mean kinetic energy of the particles is directly proportional to their absolute temperature.10. Which is defined as the combination of pressure and temperature at which all three states of matter can coexist at equilibrium?Critical pointMelting pointDeposition pointTriple point11. Which is NOT an assumption of matter made by the kinetic molecular theory of gases? Gas particles are small and take up little volume relative to the volume of the space around them.Gas particles are widely dispersed and therefore are not affected significantly by attractive or repulsive forces.When particles collide, their total energy is decreased.The kinetic energy of particles is determined by their mass and their velocity.12. Which colour curve represents the lowest temperatureBlackBlueRedPurple13. According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas? 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 separation between the gas particles is smaller than the size of the gas particles themselves.The motion of the gas particles is random and straight-line.14. A gas sample is at STP. Which changes in temperature and pressure will cause this sample to behave more like an ideal gas?Decreased temperature and decreased pressureIncreased temperature and increased pressureDecreased temperature and increased pressureIncreased temperature and decreased pressure15. For a gas, which pair of variables are inversely proportional to each other (if all other conditions remain constant)?P, TP, Vn, VV, T16. The stopper is removed from the container of chlorine, at which temperature will the gas diffuse the fastest.273 K310 K245 K290 K17. Particules will experience large velocities at ... Intermediate temperatureHigh temperatureNone of the aboveLow temperature18. Which is the state change that occurs when a solid becomes a gas without becoming a liquid first?DepositionVaporizationFreezingSublimation19. The rate of diffusion is influenced by: The color in that darker diffuse more slowlyThe size in that smaller diffuse more quicklyNone of the aboveTHe size of the molecules in that larger diffuse more quickly20. The Kinetic Theory of Matter states the following, except; All matter is composed of atomsAtoms are in constant motionMatter cannot be created or destroyedThe motion of the particles can explain their physical states21. What is the kinetic energy of a 35 g of oxygen traveling at a velocity of 650 m/s?7393.75 J7393.75 KJ7,393,750 J7,393,750 KJ22. According to the kinetic molecular theory, the particles of an ideal gasHave strong intermolecular forcesAre arranged in a regular, repeated geometric patternAre separated by great distances, compared to their sizeHave no potential energy23. Which of the following statements is false?Molecules of CH4(g) at high pressures and low temperatures have no attractive forces between each other.Van der Waal's equation corrects for the non-ideality of real gases.The properties of N2(g) will deviate more from ideality at -100oC than at 100oC.Molecules of an ideal gas are assumed to have no significant volume.24. Under which conditions of temperature and pressure does a sample of neon behave most like an ideal gas? 400 K and 25 atm400 K and 0.25 atm100 K and 25 atm100 K and 0.25 atm25.
