Energie-oordrag en stelsel

Besparing van energie

Opvoeders afdeling

Memorandum

Uit huis: Enige voorstelle. Meestes kom op insulasiemeganismes neer.

Rem: kry rem los. Papwiel: pomp die band.

Idees:

Daar is baie. Gee leerders voldoende geleentheid en laat gesprek toe.

Inhoud

Aktiwiteit: om te kan beskryf hoe energieverlies beperk kan word [lu 3.2]

Kyk weer na die illustrasie van die huis by Aktiwiteit 4.1. Gesels in 'n groepie en dink aan maniere waarop julle die energieverlies uit die huis sou kan verminder:

1. ___________________________________________________________________

2. ___________________________________________________________________

3. ___________________________________________________________________

4. ___________________________________________________________________

5. ___________________________________________________________________

X Gevolgtrekking 1: energieverlies kan verminder word deur goeie isolasie .

Dink aan die voorbeelde met die remme en die papwiel in Aktiwiteit 4.1. Hoe kan die verlies van energie in die twee gevalle verminder word?

  • Gevolgtrekking 2: energieverlies kan verminder word deur toe te sien dat sisteme goed funksioneer.
  • Gevolgtrekking 3: ons het ook gesien dat energie bespaar kan word deur die korrekte gebruik van elektriese toestelle.

Hier is 'n paar maniere om elektrisiteit in die huis te bespaar.

  • Skakel die warmwatersilinder af as julle langer as ‘n week van die huis gaan weg wees.
  • Kook water in ‘n ketel en gooi dit dan in ‘n warmfles om later te gebruik.
  • Dit is onnodig om elke keer ‘n vol ketel water te kook as jy net een of twee koppies vol nodig het.
  • Gebruik lae-energie gloeilampe.
  • Installeer sonpanele op die huis se dak.

lack electricity and its more savely than electronic microscope because its naturally by using of light
Abdullahi Reply
advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
