Study Notes • Matter&Material • Matter-everything around you‚ it is anything made of atoms and molecules. It’s anything that has a mass. Matter is related to light and electromagnetic radiation. Usually found in a few forms and it has 5 states- (Solids‚Liquids‚Gases‚Plasmas‚Bose Einstein Condensates) • Mass- It is the amount of material in an object. It is the same on Earth or Mars. It is the amount of matter which an object contains. • Weight- It is how heavy something is. It is a physical property

Sngapore’s seperation from Malaysia was caused by UMNO’s policies. The spotlight of this statement is the correspondance of the seperation of Singapore from Malaysia‚ due to the policies carried out by the United Malay National Organisation. During this post-war period‚ although Singapore was already a part of Malaysia‚ their relationship was uncertain due to the political tension and differences in ideology between Singapore and the Malayan states at that time. It has been reviewed that Source

Background examination for the Dominant Thumb Experiment: • Upon reading the literature that the researcher found by googling‚ "Thumb Dominance‚" they discovered that almost every human being has a dominant thumb whether it be the right thumb or the left thumb on top after naturally clasping their hands together. However‚ if the individual tries to force their clasped hands to let the other thumb become dominant it ’s most often described as feeling awkward or abnormal. In 1999‚ a scientist by the

separate solid particulates from fluids Filtration is a technique used to separate a solid from a liquid. The solid is separated from the liquid phase by passing the mixture over a filtering media. Filtering media is characterized by being chemically inert to the mixture‚ and having small pathways for the liquid to pass through‚ but these pathways should be smaller than the solid particle size. Filtering media can be prepared using paper‚ fritted-glass‚ or any porous material. The mixture can be

matter is neither created or destroyed and it is only rearranged 2. In chemical reactions‚ the molecules stay the same‚ they are just rearranged to form a different substance Mixtures and Substances 1. A pure substance is a substance that consists of only one component and has a definite composition 2. A mixture is two substances that are mixed but not combined chemically 3. A pure substance has only one

Mixed Melting Points | Determination of an Unknown Solid | | [Type the author name] | 9/15/2011 | Purpose : The main purpose of this experiment was to identify an unknown compound/substance by performing multiple experimental melting point tests. Pure and impure solids were tested to see what affect pureness/impureness had on a melting point. Background: The melting point of a solid can be used to determine the purity of the solid. Pure samples usually have identical or similar melting

Alexie not only shines a new light on indian life‚ but reflects upon the similarities and differences that exist between cultures. The film makes use of human emotion‚ situations and relationships to create a dramatic and truthful dynamic of the solid and figurative connections between Native America and White America. Besides these important factors‚ Alexie also touches upon the importance of family and culture. This film is not an ordinary Native American film that many are used to viewing

of atom are called mixtures. * Mixtures are made up of groups of atoms called molecules. * Molecules that are made of one type of atom are called simple molecules. Examples: O3 ‚ N2 ‚ S8 * Molecules that are made of more than one type of atom are called compound molecules.

Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to be a substance that is either

It exists in solids‚ liquids‚ gases‚ and plasmas. You can determine whether an object is a solid or not based on two characteristics. Solids have a definite shape and a definite volume. Solid’s particles are so close together that they cant move and that’s what keeps a solid a definite shape. Little motion can occur in the particle arrangement. Particles in liquids‚ however‚ can move more freely. The particles are close together but are not as tightly packed as solids are. Like solids‚ liquids have
