Kinetic Molecular Theory

Q. In the video, you can see that when heat is applied to a solid it is converted into the liquid phase and then the gas phase. This process can be studied by plotting the graph of temperature versus the time during which heat is applied to the system. Using this information, arrange the average kinetic energy of the molecules for the following options in decreasing order. Rank from highest to lowest. to rank items as equivalent, overlap them.

Kinetic Molecular Theory

Q. Which of the following observations indicates that attractive forces may exist between gas molecules?  X. Doubling the pressure on H2(g) results in halving of its volume.  Y. The measured molar volume of Cl2(g) is < 22.4 L at STP.  Z. When NH3(g) is placed under 10.0 atm pressure at 25 °C, the gas condenses into a liquid.

Kinetic Molecular Theory

Q. Which statement best describes why gases deviate from ideality? a. As gases speed up, the collisions become more powerful than are predicted. b. Gases that are too reactive do not obey the ideal gas law. c. Mixtures of gases and liquids do not behave as predicted by the ideal gas laws. d. Very large molecules travel more slowly than do small molecules. e.As gases are nearing the point at which they condense into liquids, the interactions between molecules become important.
