Memorandum

Voltooi die volgende tabel:

EIENSKAPPE VASTE STOF VLOEISTOF GAS
VOLUME Dit het nie ‘n vaste volume nie – die volume verander maklik. Dit ver-sprei en neem die spasie in wat beskikbaar is.
VORM Dit neem die vorm van die houer aan.
GEWIG Dit het gewig.

Voorbeelde van faseverandering:

  • Vaste stof na vloeistof: ys na water
  • Vloeistof na vaste stof: water na ys
  • Vloeistof na gas: water wat kook, waterdamp
  • Gas na vloeistof: waterdamp / vog wat kondenseer teen glas, bv. motor- of kombuisvensters

Inhoud

Aktiwiteit: om materiale te klassifiseer [lu 2.2, lu 2.3]

  • Wanneer stowwe in groepe met dieselfde eienskappe verdeel word, noem ons dit klassifikasie .
  • Wetenskaplikes klassifiseer verskillende materiale op verskillende maniere. Die bekendste manier is om dit volgens vaste stowwe, vloeistowwe en gasse te klassifiseer.

Voltooi die volgende tabel:

EIENSKAPPE VASTE STOF VLOEISTOF GAS
VOLUME Dit het ‘n vaste volume. Dit het ‘n vaste volume.
VORM Dit het ‘n vaste vorm. Dit neem die vorm van die houer aan.
GEWIG Dit het gewig. Dit het gewig.

‘n Stof kan van een fase na ‘n ander verander deur verhitting of afkoeling :

Gee ‘n voorbeeld van die volgende soorte fase-veranderings:

  • Vaste stof na vloeistof:

_____________________________________________________________________

_____________________________________________________________________

  • Vloeistof na vaste stof:

  • Vloeistof na gas:

Assessering

Leeruitkomste 2: Die leerder ken, interpreteer en pas wetenskaplike, tegnologiese en omgewingskennis toe.

Assesseringstandaard 2.2: Dit is duidelik wanneer die leerder inligting kategoriseer: kategoriseer voorwerpe en organismes in terme van twee veranderlikes.

Assesseringstandaard 2.3: Dit is duidelik wanneer die leerder inligting interpreteer.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct

is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
