  • Kinetic Energy Change As The Water
    3,493 words
    Thermochemistry Answer Key Assignments 1- 8 Page 1. Answers to Energy Assignment 1 1. Indicate whether the following scenarios illustrate matter possessing mainly potential energy, or kinetic energy. a) There are 30 liters of fuel in the tank of a stationary automobile. o Potential energy (chemical energy in fact) b) A large rock is perched at the edge of a 40 m cliff. o Potential energy (of the gravitational type) c) Energy is supplied to a beaker of water raising its temperature from 20 oC to ...
  • Boiling Point
    586 words
    Fractional Distillation of Crude Oil BOILING POINTS AND STRUCTURES OF HYDROCARBONS The boiling points of organic compounds can give important clues to other physical properties. A liquid boils when its vapor pressure is equal to the atmospheric pressure. Vapor pressure is determined by the kinetic energy of molecules. Kinetic energy is related to temperature and the mass and velocity of the molecules. When the temperature reaches the boiling point, the average kinetic energy of the liquid partic...
  • Kinetic Energy Of The Marble
    865 words
    Physical Science lab #5 Objective The goal of this experiment is to develop a theory, which allows us to understand the motion of a marble. Materials Wooden roller coaster, marble, ruler, timer, clamp, physics stand. Theory In this experiment, we are finding the Conservation of Energy. Energy is neither created nor destroyed. Energy is summed up into two different properties: Potential energy and Kinetic energy. The law of Energy states that: Total Energy = Potential Energy + Kinetic Energy OrEm...
  • Potential Energy In The Stretched Band
    357 words
    Energy Energy is the name given to the ability to do work. Work and energy are measured in the same units. People often confuse energy, power, and force. Force is a push or a pull on an object or body. The amount of work is determined by the strength of the force used and the distance through which it moves. Power measures the rate at which work is done. There are 2 different kinds of energy. Potential energy is often called stored energy. It represents work that has already been done. A rock ly...
  • Hcl To Diffuse Slower In The Tube
    1,857 words
    GAS LAWS KINETIC ENERGY / GRAHAM'S LAW LABChemistryBlock 8 April 20th, 2005 Purpose: To observe how masses of atoms and molecules affect their rate of diffusion, and explain our observations in terms of mass, velocity, kinetic energy and temperature. Warm-up Question: 1. What is the definition of temperature? Temperature is a measure of the average Kinetic Energy of the particles composing a material. 2. What is the definition of diffusion? Diffusion is a spontaneous spreading of particles until...
  • Kinetic And Potential Energy
    443 words
    What do we really need, energy or power? This was a question proposed to me at the beginning of the semester and it really made me think. Energy is a property of matter that can be converted into work, heat, or radiation. It is the capacity for doing work, generating heat, and emitting light or radiation. Power is the rate of spending energy or energy per unit time. Immediately, I thought the answer was energy since you need energy to have power. But then I heard that the answer was power and it...
