what is a pure substance
a form of matter with constant chemical composition and distinct, uniform properties (such as density, color, and boiling point) throughout.
what is a mixture
a mixture is when u mix two things together and then its a mixture.
what is a filtration
a physical, mechanical process that separates solid, insoluble particles from a fluid (liquid or gas) by passing it through a porous medium
what is a distillation
a widely used method for separating components of a liquid mixture based on differences in their volatilities (boiling points)
what is evaporation .
its when something is in heat .
how do people use pure substances
used in daily life, industry, and research for their predictable, reliable, and consistent properties
how do people use a mixter
In science and daily life, people use mixtures (combinations of two or more substances that aren't chemically bonded) to create materials with specific, useful properties that a single "pure" substance can't provide.
how do people use a filtration
as a "physical screen" to separate a solid from a liquid or a gas
how do people use a distillation
People use distillation to separate mixtures by taking advantage of different boiling points. Unlike filtration, which catches "chunky" solids, distillation is used to separate liquids that are blended perfectly together or to get pure water from a salty mess.
what makes a pure substance
it consists of only one type of particle—either a single element or a single compound—and possesses a constant, uniform chemical composition throughout
what makes a mixter
combine two or more substances together without changing them chemically
what makes a filtration
a mixture, a medium (the filter), and a force to push it through.
what makes a distillation,
boiling, separating, and cooling.
were did a pure substance come from
the natural formation of the universe or human-led purification.
were did a mixter come from
Just like pure substances, mixtures come from both the natural world and human invention. However, while pure substances are rare, mixtures are the "default setting" of the universe.
were did a filtration come from
it started with nature and was later copied by humans who noticed that "dirty" water became "clean" when it passed through the earth.
where did a distillation come from
Like filtration, distillation was a "nature hack" that humans observed and then spent thousands of years perfecting. Its name literally means "to trickle down in drops.
why is It called a pure substance
because it describes the "purity" of its internal structure
why is it called a mixter
It is called a mixture because of the way the different parts behave together. The name comes from the Latin word mixtura, which literally means "a blending.
why is it called a filtration
It’s called filtration because of the specific material people used to do it hundreds of years ago!
