Ghost Of Highbury:
If u take it out carefully, theres no chance of movement. whatever.
Baladya:
which is better in insulation: A piece of cloth soaked in water and wrapped around a beaker of hot water, or a piece of cloth dry (has air in it) and wrapped around a beaker of hot water?? Which is better and why in terms of molecules, kinetic energy, bla bla...
Thanks ;)
Vin:
A piece cloth soaked in water does totally opposite of insulation .. water molecules evaporate and take away the heat energy with them (the heat is used up to convert water to vapor as the kinetic energy of of molecules is enough to break the water bond) . this is good wen a body is to be kept cold .. :)
As dry cloth has air .. body stays warm as air is a bad conductor of heat ..:)

hey guyz lsn
What are the important instruments for physics ppr 6
because recently deyr have been VErnier scale and micrometer screw gauge poppin up
so all unhheard instruments can u guyz name ?
thx :P

Go to youtube and search for micrometer and vernier callipers. There will be several videos showing you how to use each.
