nanni (arn437) – LM 01 Gas Simulator Intro – vanden bout – (50985) 1 This print-out should have 5 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0points When considering the particle view of a gas, gas particles are considered to be 1. individual spheres, regardless if the gas is atom, a combination of atoms, or a combina- tion of ions. correct 2. individual spheres, only if the gas being modeled is an atomic gas, such as helium. 3. individual spheres, only if the gas being modeled is a molecular gas, such as water. 4. individual spheres, only if the gas being modeled is a relatively small gas. Explanation: Refer to the Ideal Gas Simulator intro video. 002 10.0points The gas particles move 1. towards the corners 2. in the same direction 3. in all directions correct Explanation: Gas particles in the simulator move about

Unformatted text preview: randomly. 003 10.0 points The particles change direction when 1. when they collide with each other 2. both answers are correct correct 3. when they collide with the walls oF the container Explanation: The particles change direction only when they collide when something, either another particle or the vessel wall. 004 10.0 points What do you think is between the particles? 1. Something, but the simulator doesn’t show it. 2. Smaller gas particles. 3. Nothing. correct Explanation: There is only empty space between the par-ticles in this simulation. 005 10.0 points The speeds oF the individual gas particles 1. are all the same. 2. varies. correct 3. individual gas particles change speed while moving in a straight line. Explanation: The speed oF each gas particle will vary as it moves about....
