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....
