### Model 3 – Kinetic Energies #### Graph Descriptions: **Left Graph: KE of Helium at Different Temperatures** - **X-axis (horizontal):** Kinetic Energy (Joules) - **Y-axis (vertical):** Number of Particles out of 1 Million - **Curves Represent:** - Solid line: Helium at -100°C - Dashed line: Helium at 100°C - Dotted line: Helium at 500°C This graph illustrates how the distribution of kinetic energy among helium particles changes at various temperatures. As the temperature increases, the peak of the curve shifts, indicating that more particles have higher energies. **Right Graph: KE of Noble Gas Molecules at 100°C** - **X-axis (horizontal):** Kinetic Energy (Joules) - **Y-axis (vertical):** Number of Particles out of 1 Million - **Curves Represent:** - Solid line: Helium - Dashed line: Argon - Dotted line: Xenon This graph shows the distribution of kinetic energy for various noble gases at the same temperature (100°C). The differences in the curves reflect variations in how kinetic energy is distributed across particles of different molar masses. #### Questions: 3. **What is the variable and unit of the x-axis for both graphs in Model 3?** - **Variable:** Kinetic Energy - **Unit:** Joules (J) **What is the variable and unit of the y-axis for both graphs in Model 3?** - **Variable:** Number of Particles out of 1 Million - **Unit:** Count (numeric, no unit) **What variable, temperature or molar mass, is being varied in the graph on the left?** - **Variable:** Temperature **What variable, temperature or molar mass, is being varied in the graph on the right?** - **Variable:** Molar Mass #### Explanation: Describe the relationship between the average kinetic energy of the particles in a sample and the temperature when the molar mass is held constant. Use a grammatically correct sentence.
