A pure substance is a kind of matter that cannot be separated into other kinds of matter by any physical or chemical process.
What is a Homogeneous mixture
any combination of substances that has uniform composition and properties
What is a Heterogeneous mixture
any combination of substances that does not have uniform composition and properties
OR
a mixture of physically distinct substances with different properties
What is a Solution
a gas, liquid, or solid that have other substances mixed together
What is a Mechanical mixture
A heterogeneous mixture of particles or masses distinguishable as such under the microscope or separable by filtration
What is Suspension
a system consisting of small particles kept dispersed by agitation (mechanical suspension) or by the molecular motion in the surrounding medium (colloidal suspension).
What is a Colloid
a substance made up of a system of particles with linear dimensions
What is a Element
one of a class of substances that cannot be separated into simpler substances by chemical means. See also chart under periodic table
What is a Compound
composed of two or more parts, elements, or ingredients
What is Chromatography
the separation of mixtures into their constituents by preferential adsorption by a solid, as a column of silica (column chromatography) or a strip of filter paper (paper chromatography) or by a gel
What is a phase
A par tof a Mechanical mixture
What is Pascals law
Pascal's law or the Principle of transmission of fluid-pressure states that "pressure exerted anywhere in a confined fluid is transmitted equally in all directions throughout the fluid
What is Viscosity
The amout of risistance it take for a object (Lets say a marble to fall to the bottom) The longer it takes for the marble to fall to the bottom, (Lets say to fall to the bottom of maple syrup) the longer it takes the more viscoity.
