QuestionAnswer
pure substances an element or compound
mechanical mixture two or more substances where you can easily see the two different substances
solution one substance (solute) is completely dissolved in another (solvent) and you cannot see the diffrence
solute a substance (g) that can dissolve in a solvent
solvent a substance (usually a liquid in ml) that a solute can dissolve into
concentration the quantity of a solute in a solvent
solubility how well a substance dissolves into solvent
viscosity a fluids internal resistance or friction that keeps it from flowing
density the amount of mass in a given volume
pressure the amount of force exerted on a certain area
hydraulic system a system that uses a liquid as an enclosed fluid
pneumatic system a system that uses a gas as an enclosed fluid
Pascal's law an enclosed fluid exerts pressure in all directions
unit of pressure Pascals (P)
1 Pascal = 1 Newton of pressure exerted on one square meter
saturation the point at which a solvent cannot dissolve anymore solute
matter can be divided into pure substances and mixturess
two types of mixtures are mechanical mixtures and solutions
calculating concentration grams per milliliter (g/ml)
compressable a trait of a substance at which its particles can be pushed together
incompressable a trait of a substance at which its particles are physically unable to be compressed together
compound combination of two or more elements (ex. oxygen mixed with hydrogen makes water)
water, sugar, ammonia are examples of examples of pure substances
homogeneous mixture two or more of the same substance mixed together together so that they cannot be separated or seen
heterogeneous mixture two or more of a different substances mixed that can be easily seen and can be separated with a filter
evaporation is a way of seperating a solute from a solvent by using heat
distillation is a method of separating a solution of two different liquids depending on their boiling point
unit of force Newton (N)
unit of area meter squared
buoyancy an upward force that is the opposite to gravity
insoluble when a solute cannot dissolve into a solvent
temperature the rate (speed) at which a solute dissolves into a solvent
