Inhoud

Aktiwiteit: om die drie basiese vorms van materie in terme van die deeltjieteorie te kan verduidelik [lu 2.2]

  • VASTE STOWWE
  • VLOEISTOWWE
  • GASSE

Die partikels in vaste stowwe bly op dieselfde plek en beweeg net effens. Hulle vibreer in ‘n vaste posisie. Dit is waarom vaste stowwe ‘n vaste vorm en volume het. Die partikels vorm ‘n reëlmatige patroon.

In vloeistowwe kan die partikels beweeg, maar nie ver van mekaar af nie. Hulle vorm nie ‘n vaste patroon nie en kan dus die vorm aanneem van die houer waarin hulle is. Omdat die partikels nie ver van mekaar af beweeg nie, verander die volume nie maklik nie.

Die partikels in ‘n gas kan min of meer na enige plek beweeg. Die partikels is ook baie verder van mekaar as in ‘n vaste stof of vloeistof.

OPDRAG 3

Kyk of jy die volgende drie kolomme kan voltooi deur voorbeelde van die drie vorms van materie te noem.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
