Part A) Which of the following statements is true for ideal gases, but is not always true for real gases? Choose all that apply. Molecules are in constant random motion. Pressure is caused by molecule-wall collisions. The size of the molecules is unimportant compared to the distances between them. The volume occupied by the molecules is negligible compared to the volume of the container. Part B) Which of the following statements is true for real gases? Choose all that apply....
Which of the following are not properties of ideal gases? [Select all that apply.] The gas molecules repel one another The gas molecules experience elastic collisions Kinetic energy is converted into potential energy when the gas molecules collide The gas molecules form dispersion forces with one another. The gas molecules form hydrogen bonds with each other The gas molecules are physically large, occupying a significant volume of space relative to the volume of their container.
Decide which of the following statements are true and which are false. As temperature increases, the average kinetic energy of a sample of gas molecules decreases. Ideal gas molecules have small volumes and exert weak attractive forces on one another. At constant temperature, the lighter the gas molecules, the smaller the average velocity. In order for two separate 1.0 L samples of O2(g) and H2(g) to have the same average velocity, the O2(g) sample must be at a higher temperature than the H2(g) sample. Real...
1. A sample of an ideal gas has a volume of 2.26 L at 278 K and 1.10 atm. Calculate the pressure when the volume is 1.80 L and the temperature is 303 K. 2. The volume of a sample of hydrogen gas was decreased from 10.76 L to 4.05 L at constant temperature. If the final pressure exerted by the hydrogen gas sample was 8.39 atm, what pressure did the hydrogen gas exert before its volume was decreased? 3....
