faster in different directions. Purpose: The purpose of the lab is to demonstrate the relationship between particle size and distance of movement caused by wind. Hypothesis: If the particle increases then the distance will decrease because the…

Visual Observation Dry Texture Test Wet Texture/ Rolling Test Smear Test Nutrients Quickness of drying Sand Particles visible with eye. The heaviest. Feels gritty and falls apart Crumbles No smear Few nutrients Dries quickly Does not hold water well Silt Just enough big to see them with a magnifying glass. Not as heavy as sand but heavier than clay Holds together, feels smooth and powdery Holds together, moderate crumbling, cannot be rolled in a strand Some smear More nutrients than sand Takes a…

solution the faster the reaction will take place because the particles will collide more when the temperature rises. The aim of this experiment was to test if the temperature affects the rate of reaction between hypo and dilute hydrochloric acid? How does temperature affect the rate of reaction between hypo and dilute hydrochloric acid? The kinetic particle theory explains the properties of different states of matter. The particles in solids, liquids or gases have different amounts of energy.…

bob in our progression. Truth be told, both are brought on by light dissipating through particles noticeable all around. The huge variety in the shades of night falls relies on upon the grouping of little particles, or little pressurized canned products, in the climate. Without these little pressurized canned products, the sky at dusk tackles yellow or orange tones, while expanding groupings of little particles in the lower climate further build…

This substantial distinction prompts to the loss of an electron from the less electronegative particle and the pickup of that electron by the more electronegative molecule, bringing about two particles. These oppositely charged particles feel a fascination in each other, and this electrostatic fascination constitutes an ionic bond. Ionic holding happens between a nonmetal, which goes about as an electron acceptor, and a metal, which goes about as an electron contributor. Metals have few valence…

must pay attention to. Density is how closley packed the particles in a substance are while viscosity is the resistance that a fluid has to flowing and movement. Viscosity is due to the movement of particles. The particle theory is a great tool to help us understand how viscosity works. The reason a fluid can vary in viscosity is because the greater the forces of attraction between the particles, the stronger the resistance of the particles flowing past each other will be. These terms are both…

of interdependent elements of physiological processes. To observe homeostasis, we would look into osmolarity. Osmolarity is a concentration measurement of particles using milliosmoles per liter (mOsm/L). The difference between molarity and osmolarity is that osmolarity takes pressures into account. Osmolarity only calculate the amount of particles difference between the intracellular membrane and the extracellular of the membrane. The…

Within that spectrum the wavelengths visible to humans are few. Light is very difficult to define, in the sense that scientist have been arguing weather light is a particle or a wave. Many experiments have been done to proof weather light is a particle or a wave. The truth is that light sometimes acts as a wave and sometimes as a particle. In the famous Young's double-slit experiment, a coherent beam of light is directed through two slits and then onto a photographic plate. When each photon hits…

1.2. How Far? Entropy What is entropy? The interaction of energy and matter governs our lives. We take for granted our ability to use chemicals in batteries to produce sound from MP3 Player. We get into a car and use petrol to travel in hours distance that would have taken our ancestors days. Energy and matter interact on other scales too –from the remnants of the explosion of star hundreds of light years in diameter, to the nucleus of an atom 10-9 mm in diameter. The way in which energy and…

radioactivity in particles exists in at least two forms. In the experiment tiny alpha particles were shot at a sheet of foil coated in ZnS which resulted in a small percentage went through the sheet and the rest were blocked/deflected. The percentage of particles that were able to go through the foil are now named 'Alpha Particles' and the ones that were blocked are called 'Beta Particles'. He was able to tell the difference between Alpha and Beta particles because he knew that when a particle…
