Problem
A sealed cylinder initially contains 0.80 mol of an ideal gas in a 2.00 L volume at 320 K. The cylinder is fitted with a movable piston. The gas is heated to 480 K while the piston is adjusted so that the pressure remains constant throughout the heating.
Answer the following, justifying each response in 1–2 sentences:
(1) Is the average spacing between gas particles at the end of the process greater than, less than, or equal to its initial value?
(2) Is the collision frequency of gas particles with the cylinder walls at the end of the process greater than, less than, or equal to its initial value?
