Question
**Kinetic Theory of Gases: Effects of Changing Conditions on Neon Gas** Consider a 1.0-L container of neon gas at STP (Standard Temperature and Pressure). This exercise explores how different conditions affect the average kinetic energy, average velocity, and frequency of collisions of gas molecules with the walls of the container. **a. The temperature is increased to 220°C:** - **Average kinetic energy:** - Choices: [Increases, Decreases, Remains the same] - **Average velocity:** - Choices: [Increases, Decreases, Remains the same] - **Collision frequency:** - Choices: [Increases, Decreases, Remains the same] **b. The temperature is decreased to -70°C:** - **Average kinetic energy:** - Choices: [Increases, Decreases, Remains the same] - **Average velocity:** - Choices: [Increases, Decreases, Remains the same] - **Collision frequency:** - Choices: [Increases, Decreases, Remains the same] **c. The volume is decreased to 0.3 L:** - **Average kinetic energy:** - Choices: [Increases, Decreases, Remains the same] - **Average velocity:** - Choices: [Increases, Decreases, Remains the same] - **Collision frequency:** - Choices: [Increases, Decreases, Remains the same] **d. The number of moles of neon is tripled:** - **Average kinetic energy:** - Choices: [Increases, Decreases, Remains the same] - **Average velocity:** - Choices: [Increases, Decreases, Remains the same] - **Collision frequency:** - Choices: [Increases, Decreases, Remains the same] For each condition, use your understanding of the kinetic theory of gases to determine the correct choice for each parameter. **Instructions for Educators:** - Encourage students to think about how temperature affects the kinetic energy of the gas particles and their velocity. - Discuss how changing the volume of the container or the number of moles of gas can influence the pressure, temperature, and therefore the frequency of collisions with the container walls. - Relate these concepts to real-world applications, such as how temperature changes affect the behavior of gases in different environments.
