1. In the kinetic-molecular theory of gases, gas molecules are considered to have ______ volume and ______ attraction for each other. A) Negligible, significant B) Significant, negligible C) Significant, significant D) Negligible, negligible Answer: A) Negligible, significant Rationale: According to the kinetic-molecular theory, gas molecules have negligible volume and exhibit significant attraction for each other. 2. True or False: According to the ideal gas law, the pressure of a gas is directly proportional to its volume when the temperature and amount of gas are held constant. Answer: True Rationale: The ideal gas law states that pressure is inversely proportional to volume when the temperature and amount of gas are held constant. 3. A gas at a constant pressure will exhibit an increase in volume when: A) The temperature increases B) The temperature decreases C) The number of gas molecules decreases D) The number of gas molecules increases Answer: A) The temperature increases Rationale: According to Charles's Law, the volume of a gas is directly proportional to its temperature when pressure is held constant
