Democritus suggested that matter is made up of tiny particles too
small to be seen. He thought that if you kept cutting a substance into
smaller and smaller pieces, you would eventually come to the
smallest possible particles—the building blocks of matter.
Many years later, scientists came back to Democritus’ idea and
added to it. The theory they developed is called the  particle model
of matter.

 2. The particles of matter are always moving 
 3. The particles have spaces between them 
 4. Adding heat to matter makes the particles move faster. ]]> 2018-10-30 05:38:58 UTC https://padlet.com/fatimajoullemk/estlewj43xjf/wish/298356601 Arrangement of Particles In Solid,Liquid and Gas fatimajoullemk https://padlet.com/fatimajoullemk/estlewj43xjf/wish/298356837 Liquid:
The particles of liquid have spaces not too big between them that allow them to flow.

Solid:
The particles of a solid are very tightly packed together and they have no spaces between them that does not enable the solid to flow.

Gas:
The particles of a solid are widely spaced and gases can flow and be compresses as well.]]> 2018-10-30 05:41:15 UTC https://padlet.com/fatimajoullemk/estlewj43xjf/wish/298356837 Brownian Motion fatimajoullemk https://padlet.com/fatimajoullemk/estlewj43xjf/wish/298357380 Brownian motion or pedesis (from Ancient Greek: πήδησις /pέːdεːsis/ "leaping") is the random motion of  suspended in a fluid (a liquid or a gas) resulting from their collision with the fast-moving molecules in the fluid. It was devised by Robert Brown,a scottish scientist.]]> 2018-10-30 05:47:18 UTC https://padlet.com/fatimajoullemk/estlewj43xjf/wish/298357380 Diffusion fatimajoullemk https://padlet.com/fatimajoullemk/estlewj43xjf/wish/298357880 Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential) as a result of random motion of the molecules or atoms.]]> 2018-10-30 05:50:15 UTC https://padlet.com/fatimajoullemk/estlewj43xjf/wish/298357880
