    Law of Diffusion of Gases

    • 689 Words
    • 3 Pages

    Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements

    Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

    Experiment 1 The Heat Capacity Ratio of Gases Purpose The purpose of this experiment is to calculate the heat capacity ratio of gases‚ Helium‚ Nitrogen and Carbon Dioxide‚ and compare with their theoretical values. Introduction Thermodynamics is the study of heat as it relates to energy and work. There are various properties which all relate to each other when determining the characteristic of a certain substance. One of such properties is heat capacity‚ which is the amount of heat energy

    Kinetic theory of gases Question: How does odor travel from one place to another? Kinetic theory of gases A gas is composed of atoms or molecules The gas particles are in constant random motion Kinetic energy is transferred between particles as they collide Pressure The force exerted per unit of area Formula: pressure/force area Measured by barometer A vacuum is empty space‚ with no particles or pressure. Atmospheric pressure is the collision air particles with objects Units of

    • 2 Pages

    1)What are all of the greenhouse gases? There are four greenhouse gases that trap and absorb heat on Earth so living organisms can sustain life. Not only are they the greenhouse gases up also make up the 1% in the atmosphere. The greenhouse gases include water vapor (H2O)‚ carbon dioxide (CO2)‚ methane (CH4)‚ and nitrous oxide (N2O). H20 - this is one but it not really talked about on the website 2) Which one is completely human related? (meaning it is not found naturally in the environment)

    OBJECTIVE: The purpose of this experiment is to practice the addition of vectors graphically and analytically and to compare the results obtained by these two methods. APPARATUS: Cenco force table with pulleys. Metal ring‚ strings‚ weight hangers and weights. Rulers and protractors. The force table provides a means for applying known forces at one or more points and in various directions in the horizontal place. The forces are the tensions in strings which pass over pulleys attaches to the
