![]() ![]() What is the difference between a heterogeneous mixture and a homogeneous mixture? Give an example of each.Classify each as being element, compound, heterogeneous mixture, or homogeneous mixture (solution): air at Furman University, Furman Lake water, copper wire, and Furman tap water.Vaporization - the phase change from liquid to gas.\): Phase Changes Change Temperature - a measure of the random kinetic energy in a sample of matter. Sublimation - when a solid transistions into a gas without going through the liquid phase. Solution - a combination of two or more substances that have uniform composition and chemical properties throughout also known as a homogeneous mixture. ![]() Reactivity - the relative ability of a substance to undergo a chemical reaction. Types include color, odor, texture, boiling point, melting point, and density. Physical property - a characteristic that can be observed or measured without changing the chemical makeup of a substance. Physical change - a change which alters a substance without altering its composition. ![]() Phase change - a special type of physical change in which a substance transitions among the states of matter, solid, liquid, and gas, but the chemical properties of the substance remain the same. Mixture - a combination of two or more pure substances in which each pure substance retains its individual chemical properties. Melting point - the temperature at which a solid turns into a liquid. ![]() Melting - when a solid turns into a liquid. Matter - anything that has mass and takes up space. Malleability - how readily a material's shape can be changed. Intermolecular force - any force that can hold or repel particles. Homogeneous mixture - a combination of two or more substances that have uniform composition and chemical properties throughout also known as a solution. Heterogeneous mixture - a combination of two or more substances in which the original substances are separated into physical distinct regions. Alloy - a homogeneous mixture of metals, or a mixture of a metal and a non-metal in which the metal is the major component.īrittleness - a material's ability to absorb energy before fracturing.Ĭhemical change - any change that results in the formation of a new chemical substance.Ĭhemical property - a characteristic of a substance that's observed during a chemical reaction.Ĭhromatography - parts of a mixture are separated based on the ability of each dissolved component to travel through materials at different speeds.Ĭombustibility - occurs when a material catches fire at a temperature above 43 degrees celcius.Ĭompound - any substance formed from two or more elements that have been joined together chemically.Ĭondensation - the phase change that occurs when water vapor cools down to form liquid water.Ĭondensation point - the temperature at which a gas turns into a liquid at standard pressure.Ĭrystallization - the separation of a pure solid substance from a solution containing the dissolved substance.ĭensity - the amount of mass per unit volume.ĭeposition - when a gas changes directly into a solid without going through the liquid phase.ĭistillation - the process that separates homogenous mixtures based on the different boiling points of the substances.Įnthalpy - the amount of heat in a system at constant pressure.Įvaporation - occurs on the surface of a liquid as it changes into a gas.įiltration - a physical process used to separate solids from liquids by passing them through a barrier.įlammability - occurs when a material catches fire at a temperature below 43 degrees celcius.įreezing - when a liquid turns into a solid.įreezing point - the temperature at which a liquid turns into a solid. ![]()
