Subject:Chemistry Topic:States Of Matter What is matter? Matter is anything that has mass and occupies space. All matter can exist in three(3)states. There are: solid‚ liquid and gas. In addition‚ all matter is made up of particles: atoms‚ molecules and ions. Solids In the solid state state‚ the particles are packed closely together in a regular manner. The focus of attraction between these particles are very strong and as a result solids are usually very hard and very difficult to compress

CHLORIDE‚ SAND the wt. of mixture with evaporating dish after 1st heating is?? g. And after Its 2nd heating?? g. The method used to separate that mixtures are Filtration and Evaporation. Filtration is the process of separating the solid from the liquid by using a porous filter. And Evaporation is the process of reducing the volume of a solution. The substances that separated are the sand and the salt. What is the purpose of adding water to the residue (the solid particles that remained on the

agent or sulficant is concentrated sulfuric acid but‚ sulfurtrioxide‚ chlorosulfonic acid‚ metallic sulfates‚ and sulfamic acid are also occasionally used. The name sulficants comes from these molecules moving to the surface of a liquid or to an interface between two liquids and changing the properties of the surface. However‚ the nature and properties of sulfuric acid‚ makes it desirable to use it for nucleophilic substitutions whenever possible. For each substance being suflinated‚ there is a critical

method would consistently test the foam and ensure it has the correct density? Background: There are words that need to be understood before executing the experiment. The first thing you need to know is density. Density is a measure of mass per unit of volume. The reason for testing density of doors because doors must contain a density of 14.34lbs per ft3 of foam‚ or it will collapse if the density is too high. If the density is too low‚ it won’t allow for normal expansion during weather changes

was calculated to be 45.76g. The error of the carried out experiment was calculated to be 20.06%. Introduction: A substance requires energy to change from one phase state to another‚ or in other words‚ when it goes from either a solid to liquid or liquid to gas. The potential energy that is stored between molecules of the substance needs to be overcome by the kinetic energy of the motion of the particles before the substance can undergo the phase change. The temperature of a substance as heat

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

In the novel Catalyst by Laurie Halse Anderson‚ there are three main sections‚ Solid‚ Liquid‚ and Gas. The main character‚ Kate‚ is very interested in science and the three titles are a metaphor for her state of mind throughout the book. The first section‚ Solid‚ shows how Kate is a stable and strong person. The next section‚ Liquid‚ is a time where Kate’s life is very inconsistent and she is unsure about herself. The last section‚ Gas‚ shows how Kate has accepted her fate and tries to help everyone
