Gizmo: Student Exploration - Temperature and Particle Motion - 2022/2023 Lab Gizmo Temperature and Particle Motion Gizmo Packet Pages 82-85 Student Exploration: Temperature and Particle Motion Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Why is hot air hot? This is because there is more heat in the air 2. Why is cold air cold? There is an absence of heat in the air. 3. Air consists of tiny particles called molecules. How do you think the molecules move in hot and in cold air? I think molecules in hot air move faster and the molecules in cold air move slower. Gizmo Warm-up The Temperature and Particle Motion Gizmo illustrates how the molecules of gas move at different temperatures. In this Gizmo, temperature is measured on the Kelvin scale, which measures temperature from absolute zero, the coldest possible temperature (-273.15 °C). Each unit on the Kelvin scale is equivalent to 1 °C: 273.15 K = 0 °C, and 373.15 K = 100 °C. 1. Describe the motion of the hydrogen molecules: The molecules are moving fast 2. Are all of the molecules moving at the same speed? No, some are moving slower than others Question: How is the temperature of a gas related to the motion of gas molecules? 1. Observe: Move the Temperature slider back and forth. Focus on the particle motion at left. What do you notice? Cooler temperatures cause the molecules to move slowly and the warmer temperatures cause the molecules to move quicker.
