When you push down on a bicycle pump, but do not let the air escape through the hose, what happens inside? The air molecules move faster. The air molecules move farther apart. The air molecules move closer together. The air molecules move slower. View Feedback on 2 1 / 1 point Detectors in the walls of four containers (A, B, C, D) count the number of collisions between gas molecules and the surfaces of the containers. The detectors count 10, 15, 20, and 30 collisions per second for containers A, B, C, and D, respectively. Which container has the highest pressure? A C D B View Feedback on 3 1 / 1 point Rebecca needs to conduct her experiment at STP. Which of the following conditions must she use? 100 K, 273 kPa 273 K, 100 kPa 100 K, 273 Pa 273 K, 100 Pa View Feedback
on 4 1 / 1 point A pump contains 0.5 L of air at 203 kPa. You draw back on the piston of the pump until the pressure reads 25.4 kPa. What is the volume of air in the pump? 4.0 L 2.0 L 0.2 L 1.0 L View Feedback on 5 1 / 1 point You have 0.5 L of air at 203 K in an expandable container that allows for a constant pressure. You heat the container to 373 K. What is the volume of air? 0.67 L 2.7 L 0.27 L 0.92 L View Feedback
