everything is made up of matter. Matter is everything you see, hear, touch, and taste.
all elements are in the periodic table. an atom has 3 main parts
proton, neutron, and electron. the change of state it goes from solid
to a liquid to a gas. they way that happens is the bons between
spererate. amd they keep seperating in till it gets to all stages solid,
liquid, gas.
As you can see from the picture. solidof all the atoms are very tight and in the liquid they are in the middle they are starting to expand, and then gas they are fully expanded. particals are always moving, adding heat to matter makes them mover faster, and adding cold to tehm makes them slower. this is how the change of state goes in, like the order.
solid: it has a fixed shape beacause the volume can only move a little bit. melting: a solid has heated and the particals move faster in till it melts. freezing: the energy moves slower so it gets colder and freezes. liquid: it takes shape of the container, beacuse the particals can move freely. evaporation: when liquid absorbs heat, and changes into a gas. condensation: the gas cools, and changes back into a liquid. gas: gas particals are seperated alot, there for gas, is empys space. but it always fills whatever shape/container its in. we also learned about chemical recations. a chemical recation is a substance or substances involved into a chemical recation. and all pure subastces are elements, and all the elements are in the peridoic table above. |
