According to the kinetic molecular theory, the particles of an ideal gasAre arranged in a regular, repeated geometric patternHave strong intermolecular forcesHave no potential energyAre separated by great distances, compared to their size2. Which state of matter exhibits only vibrational movement?LiquidSolidPlasmaGas3. In a real gas particles have complete inelastic collisions meaning no energy is lost. TrueFalse4. Which postulate of KMT explains why the scent of fresh coffee in the morning fills up every room in the house?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.4‐ The mean kinetic energy of the particles is directly proportional to their absolute temperature.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.5. Which is the state change that occurs when a solid becomes a gas without becoming a liquid first?SublimationDepositionFreezingVaporization6.

Which postulate of the KMT explains why the smell of skunk spray can seep into a house even when the windows are closed. 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.4‐ The mean kinetic energy of the particles is directly proportional to their absolute temperature.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.11. The rate of diffusion is influenced by: None of the aboveThe color in that darker diffuse more slowlyTHe size of the molecules in that larger diffuse more quicklyThe size in that smaller diffuse more quickly12. Which is the term used to describe the energy required to increase the surface area of a liquid? ViscositySurfactantDepositionSurface tension13. Which is NOT an assumption of matter made by the kinetic molecular theory of gases? The kinetic energy of particles is determined by their mass and their velocity.Gas particles are small and take up little volume relative to the volume of the space around them.When particles collide, their total energy is decreased.Gas particles are widely dispersed and therefore are not affected significantly by attractive or repulsive forces.14.
