1) What is the definition of a mixture? a) two or more materials stirred together b) a special mixture formed when a material dissolves in water. c) a characteristic of an object, something you can observe such as size, color, shape or texture d) a liquid turns into a gas and disperses into the air, leaving any dissolved solids behind. 2) What is the definition of solution a) a liquid turns into a gas and disperses into the air, leaving any dissolved solids behind. b) the solid form of a material that can be identified by its properties such as shape, color, and pattern c) a special mixture formed when a material dissolves in water. d) two or more materials stirred together 3) what is the definiton of property a) the solid form of a material that can be identified by its properties such as shape, color, and pattern b) use coffe filters and screens to separate c) a process in which one material disperses uniformly into another material so it seems to disappear. d) a characteristic of an object, something you can observe such as size, color, shape or texture 4) what is the definition of Dissolving  a) a process in which one material disperses uniformly into another material so it seems to disappear. b) a characteristic of an object, something you can observe such as size, color, shape or texture c) a special mixture formed when a material dissolves in water. d) the solid form of a material that can be identified by its properties such as shape, color, and pattern 5) what is the definition of evaporation  a) a process in which one material disperses uniformly into another material so it seems to disappear. b) : a liquid turns into a gas and disperses into the air, leaving any dissolved solids behind. c) a special mixture formed when a material dissolves in water. d) the solid form of a material that can be identified by its properties such as shape, color, and pattern 6) what is the definition of crystal a) : a liquid turns into a gas and disperses into the air, leaving any dissolved solids behind. b) the solid form of a material that can be identified by its properties such as shape, color, and pattern c) a special mixture formed when a material dissolves in water. d) a process in which one material disperses uniformly into another material so it seems to disappear. 7) Which does NOT belong with mixtures? a) light will always pass through  b) can be separated  c) use coffe filters and screens to separate 8) Which does NOT belong with solution a) light will always pass through b) can be separated c) use coffe filters and screens to not separate 9) three ways to separate a mixture a) screen ,filter ,evaporation b) glass,paper,napkin c) screen, cup, bowl 10) which is the definition of saturation a) When no more solid material will dissolve b) solid material like salt c) when more solids dissolve
