What is the particle theory? The particle theory says that that matter consists of many small particles with spaces in between. The particles are constantly moving‚ the higher it’s temperature‚ the faster they move. All the particles are attracted to each other. The particles move faster and move further apart when heated‚ and the reverse when cooled. Each substance has unique particles that are different from the particles of other substances. Particle theory helps to explain the behaviour of

Gaussian Mixture Models∗ Douglas Reynolds MIT Lincoln Laboratory‚ 244 Wood St.‚ Lexington‚ MA 02140‚ USA dar@ll.mit.edu Synonyms GMM; Mixture model; Gaussian mixture density Definition A Gaussian Mixture Model (GMM) is a parametric probability density function represented as a weighted sum of Gaussian component densities. GMMs are commonly used as a parametric model of the probability distribution of continuous measurements or features in a biometric system‚ such as vocal-tract related

05.05 Mixtures and Solutions Background: Paper chromatography is one method for testing the purity of compounds and identifying substances. Paper chromatography is a useful technique because it is relatively quick and requires small quantities of material. Safety: Warnings: * Rubbing alcohol (or isopropyl alcohol) is flammable‚ so be sure to keep it away from high heat or heat sources. * Keep pigments and solutions away from your eyes‚ wash your hands carefully after coming in contact

Students at NFV middle school are on a journey to figure out a mystery mixture. They have to search through 9 chemicals to figure out which one is it. Seems easy huh? Nope‚ they have to analyze the physical and chemical properties (a very important part in this)‚ the data‚ argue‚ and give important statements on what they think is in the mix. That’s when arguing comes in‚ not arguing on the person but the statement. I think it is citric acid and baking soda. Eighth graders have to find out what

O’Brien’s Honors Science class we conducted two experiments the Mixed Substances Lab and the Investigating Mixtures Lab. The objective of the Investigating Mixtures Lab was “To observe that not all liquids behave the same way when mixed with other liquids”. Before we started the lab we we each created a hypothesis mine was “If the water and vegetable oil are mixed and the two combine and make a mixture‚ then the vegetable oil will float and the water will sink”. This is the important information which

RULES OF MIXTURES FOR ELASTIC PROPERTIES The paper is about the rules of mixtures which are used to express the dependencies of the physical properties and mechanical properties which depend on type‚ form‚ quality and arrangement of its constituents‚ but they are based on various assumptions so one should with caution‚ especially if they are used anything more than preliminary design. The paper mainly concentrates on expressions for elastic properties which are as follows: Unidirectional Ply-

the pineapple into a thick‚ pulpy mixture of fresh pineapple. You need about a cup of this mixture. 2. Prepare the Jell-O as described in the directions on the box. 3. As you are boiling the water for the Jell-O‚ take a tablespoon of the thick‚ pulpy pineapple mixture and pour it into one of the three small bowls. Save that tablespoon for use with that bowl only. Mark the bowl as “room-temperature pineapple juice.” 4. Take the rest of the thick‚ pulpy mixture and pour it into a pot. You will

Theory: Distillation is the conversion of a mixture of substance into vapors which is afterwards condensed to the liquid form. It cans separation or purification of substances by taking advantage of differences in volatility. The purpose of this lab is comparing the efficiency of two distillation methods with the mixture of ethanol and 1-butanol. in theory the fractional distillation should be more efficient because of the steel sponge. The sponge acted as surface area for gas to condense on. This

Paper chromatography is used to break down colors with using water and the way the colors separate. 2. Doctors can use it to test for alcohol in people’s blood. People can also use it to check for pollutants in the water. Pharmacists can use it to find out how much of each chemical is in each product. 3. I searched

Separation of Mixture of Solids - Experiment 3 Date: 9/21/13 Purpose: This experiment is designed to show the different ways to separate solid mixtures into individual elements. It will also determine whether a substance can be considered “pure” or not‚ as well as determining the solubility of each mixture in water. Procedure: 1) Weigh the amount of the mixture on the digital scale. Separate the Iron out by using a magnet to filter out the Iron element. 2) Take the remaining mixture and add 50ml
