The theory describes gas as volume less particles in constant, random motion that exhibit no intermolecular attractions and undergo completely elastic collisions with each other and with the walls of the container. Essentially that larger particles would have an easier change to hit another particle since it's bigger but since it's slower the pressure equalizes in some way.). 3,200,000 J c. 3.2 kJ d. 3,168,750,J e. 23 kJ After colliding, objects are deformed and lose some kinetic energy. I believe this is the case because while the heavy particle would exert pressure over a bigger area, they are slow moving and as a result have less collision with each other and the walls of the container. (They collide with each other and with the walls of the container. If Nellie Newton pushes an object with twice the force for twice the distance, she does. 3. 30 seconds . Assuming that the container is expandable, the volume would continue to increase until the pressure returns to it's original value. (Rewrite of the mass/size argument with pressure above) Experiment 4, The molecule size doesn't matter. It is commonly indicated in degrees (°C/°F). One particle may be moving faster after a collision while the other ones moves slower. You always get 8 slices, but some of those slices might be cheese, while others might be pepperoni… Learn vocabulary, terms, and more with flashcards, games, and other study tools. Dec 18. Here's how it's done. The cars couple together. In this lab, you let gravity do work on a dynamics cart and compare the work done on the cart to the cart's kinetic energy. Kinetic and thermodynamic enolates. Fill out data table and graph results. As just mentioned, a hanging mass will be used to supply the force, so if the mass is m, then F net = mg. First, you can start the cart from rest, so that its initial kinetic energy is zero. Equilibrium. The lighter/small particles would have a higher kinetic energy but they are smaller. Planner: Pendulum Lab Investigation with focus on Mass vs Kinetic Energy. The kinetic energy before and after the system was then computed using the following equation. The pressure decreases because since the amount of space the particles can be in increases, the particles would be colliding with each other less frequently and as a result, the pressure decreases. It is the measurement of the intensity of heat energy. Identify the type of collision. The rapidly moving molecules that compose a gas also have kinetic energy, but this kind of energy associated with random motion is normally treated separately and called thermal energy. a. (This means that no energy is gained or lost during the collision. What is a mixture of gases' total pressure equal to? What is the relationship between pressure and amount of gas? When the amount and temperature are held constant, the pressure and volume are inversely proportional. 6.
