2008 Background Information Liquids are all around us. Every day we drink and eat items that contain liquids‚ we use liquids to clean ourselves and our belongings and liquids can even be found in the places that we would not expect‚ like televisions. When someone watches liquid over time‚ an interesting thing begins to happen. The liquid will slowly start to disappear. The formal term for the liquid disappearing is evaporation. According to Asminov‚ Liquids are a state of matter that will take

Chemistry Chapter 13 Outline Condensed phases: the liquid and solid phases; phases in which particles interact strongly. 13.1 Gas condensed when cooled and compressed. In the liquid state the forces of attraction among particles are great enough that disordered clustering occurs. It is hard to compress a liquid. Liquids diffuse into other liquids with which they are misicible. The natural diffusion rate is slow at normal temperatures. Cooling a liquid lowers its molecular kinetic energy. Solidification

mixture that would be Solid/Liquid would be Skim milk. Although skim milk contains mostly water it also contains casein‚ which is a small protein. The casein protein is so small it may not be thought to be a heterogeneous mixture‚ but if the skim milk curdles the mixture can be separated. A Solid/Liquid solution could be Seawater. The seawater is homogeneous which makes it a solution. The mixture of oil and vinegar to make a vinaigrette salad dressing is a Liquid/Liquid heterogeneous mixture. Due

Chemistry Lab Report Practical #1 Title: The Densities of Liquids and Solids Date: 29th of August 2014 Session: Friday 1 p.m. Student’s name: Alua Sarybay Lab partner’s name: Gulzhauhar Nurdildayeva Tutor’s name: Eugene Douglass Introduction The matter can be observed by determining‚ measuring and monitoring its chemical and physical properties. In this experiment the densities of liquids and solids will be determined. The density is an intensive property of matter that does not depend

to absorb liquids. It doesn’t matter if the sponge is from the sea‚ or from a factory‚ they both use wicking and surface tension in order to absorb sponges. This use is what allowed the sponge to soak its way into history. Sponge absorption is the key power that utilizes wicking and surface tension to soak up liquids. Wicking‚ or capillary action‚ allows water to be stored in sponges when they soak up liquids. According to World Book Student‚ capillary action is the movement of liquid in tiny holes

INTRODUCTION Colligative properties In liquid solutions‚ particles are close together and the solute molecules or ions disrupt intermolecular forces between the solvent molecules‚ causing changes in those properties of the solvent that depend in intermolecular attraction. For example‚ the freezing

DETERMINATION OF BOILING POINTS Introduction: The boiling point of a compound is the temperature at which it changes from a liquid to a gas. This is a physical property often used to identify substances or to check the purity of the compound. It is difficult‚ though‚ to find a boiling point. Usually‚ chemists can only obtain a boiling range of a 2 - 3oC accuracy. This is usually sufficient for most uses of the boiling point. Purpose: The purpose of this experiment is to determine the
