Assalam-o-Allaikum and Hi everyone ,
hope u all are doin great !
Well as the topic says help for chemistry biology and Physics is available here that means that u can ask any mind blowing question or ask any question regarding a particular topic or ask abt any questions from Past paper or any of your text books.
I made this topic so that people dont make many posts asking abt bio,physics or chemistry individually but they can post their reply here where it can be answered with ease and the members wont have to go searching for topics to help! !
So what are u waiting for now write ur questions here !
THANKS and Bye or Allah Hafiz ! :wink: :good:

account for the following :
a ) a saucepan used in cooking has a low heat capacity.
b ) on a clear sunny day , the temp of the surface of the sea rises less rapidly than the temp of nearby land .
Ans a: Heat transfer will take place through both convection and conduction; more effective.
Ans b: Radiation will only heat the surface of the water, this will not affect the rest of the water because convection currents do not travel downwards; therefore it remains relatively cool.
account for the following :
a ) a saucepan used in cooking has a low heat capacity.
b ) on a clear sunny day , the temp of the surface of the sea rises less rapidly than the temp of nearby land .
a so that its temp increase quickly and can help cooking
b . becox heat of capacity of land is greater than that of sea
copper metal gives electrons at positive terminal(anode) to become Cu2+ ions. the ions then travel to the negative terminal(cathode) where they gain electrons and turn back into copper metal. Remember that the object to be plated is always made the cathode(connected to -ve terminal)http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Chemistry (0620)/0620_s08_qp_1.pdf
Why is number 12 A and not B?
yeh 7 - chapters kia cheez hai?yayee..
yeah sorry i meant that only xDi think that the heat capacity of land is less than the heat capacity of sea, that is y it heats up quickly!
dude, there are no fixed marks. they change it every yearAnyone know how many marks we need to score in all 3 papers (for all 3 sciences) for an A*?
check karlo..yeh 7 - chapters kia cheez hai?
