Dear students, good morning
Today's topic in physics : 11.thermal Energy transfer - conduction
Pg.no : 150 & 151
The important points are
Conduction - thermal energy transfer from hotter object to cooler objects
1.metals are good conductors of heat
For example iron,steel
2.non metals are good insulators .
For example plastics
In figure 11.3
3.look at table 11.1
It clearly explains which are best and worst conditions
4.why metals are good conductors ?
Because they have electrons
No homework
