Document Content and Description Below

Student Exploration: Boyle’s Law and Charles’s Law Vocabulary: absolute zero, Boyle’s law, Charles’s law, Gay-Lussac’s law, Kelvin scale, pressure Prior Knowledge Question (Do this BEFORE ... using the Gizmo.) A small helium tank measures about two feet (60 cm) high. Yet it can fill over 50 balloons! How can such a small tank contain enough helium to fill so many balloons? The gas in the tank is under a lot of pressure, so a lot of gas can be fit in the tank. Gizmo Warm-up The Boyle’s Law and Charles’s Law Gizmo shows a container of gas. Inside, small purple spheres represent gas molecules. 1. Observe the particles. Are they all moving at the same speed? No, the speeds are different 2. How do the particles interact with the walls and lid of the container? The bounce off of the walls and the lid These interactions contribute to the pressure on the walls of the container. Pressure is defined as force per unit area. The SI units of pressure are newtons per square meter (N/m2 ), or pascals (Pa). 3. Slowly drag the temperature (T) slider back and forth. (Note: In this Gizmo, the Kelvin scale is used to measure temperature. On the Kelvin scale, 0 degrees is absolute zero, the coldest possible temperature. Absolute zero is equal to -273.15 °C or -459.67 °F) A. How does the change in temperature affect the speed of the molecules? The molecules move faster 2018 B. How does the change in temperature affect th [Show More]
