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

Individual solid particles are characterised by their size‚ shape‚ and density. 1.1 Particle shape The shape of an individual particle is expressed in terms of the sphericity F s‚ which is independent of particle size. The sphericity of a particle is the ratio of the surface-volume ratio of a sphere with equal volume as the particle and the surface-volume ratio of the particle. For a spherical particle of diameter D p‚ F s =1; for a non-spherical particle‚ the sphericity is defined as Dp:

Tutorial 1: Atomic Structure and Bonding in Solids 1. (a) Cite the difference between atomic mass and atomic weight. (b) Silicon has three naturally-occurring isotopes as shown in the table below. On the basis of this data‚ confirm that the average atomic weight of Si is 28.0854 amu. |Silicon Isotope |Natural Abundance |Atomic mass of | | | |isotope (amu) | |28Si |92.23 % |27.9769 | |29Si

LS Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized

Combustible Liquids (Examples: alcohols‚ esters‚ ethers‚ ketones) Vapors from flammable and combustible liquids can mix with air and burn if they contact an ignition source. Possible ignition sources include hot electrical wires‚ hot surfaces‚ open flames‚ hot particles and embers‚ and sparks. The lowest temperature at which a liquid releases enough vapor to start burning is called the flash point. The flash point is what distinguishes a flammable liquid from a combustible liquid. Flammables:

part (i) (a)‚ the solid copper(II) nitrate is used to dissolve in a test tube filled with half distilled water. The solid copper(II) nitrate ionize in water to form copper(II) ions and nitrate ion. Hence‚ a blue solution is formed due to the blue copper(II) ion present in the solution. When excess solid is added‚ the solution will become saturated and do not allow any solid to dissolve‚ so excess solid will remain in the solution. This is shows that the equilibrium between solid and aqueous copper(II)

NANCY MARASHI. | Background: During this experiment students will take a mixture and separate it into its’ pure substances. A mixture is a combination of two or more substance. These substances cannot be combined chemically but more physically. The pure substances are substances that cannot be separated any more by physical means. The students

1. Why do some scientists believe that there might have been life on Mars? Some scientists believe there was life on Mars due to a number of factors. For one we know there was at one point a substantial amount of liquid water when the planet was much younger. We also know Mars’s electromagnetic field has dampened‚ making it more susceptible to interstellar heat and radiation‚ thus eliminating the life that could have existed. There are also other several factors including volcanic activity and evidence
