:devil: did you take into account water's exceptionally large heat capacity?

source:british physics olympiad :cool: a beaker of water has a piece of ice floating on its surface.When the ice melts,show that (by logic or by equations) 1.that the water level remains unchanged. 2.If a coin was initially kept above the ice block what chang will be there in answer to 1...

we should not talk about trivial matters like one or two pots or pressure dependencies.Let us take a single pot:biggrin: let us boil eggs there.Then some analysis in entropy of the egg has to be done as the proteins in the yolk become uncoiled.LET us take into account the specific heat...

source:british physics olympiad 1993 :smile: it is said that it takes as long to boil one egg as it takes to boil two eggs. comment on the statement indicating the conditions under which it is valid? can someone give me the mathematical analysis of the problem?:biggrin:

in order to give define the rate and concentrations of reactants and products at given time we need to define a rate law similarly motion has to be analyzed in terms of differential equations in order to describe any type of motion.:-p

:rolleyes: thanks for providing that link.But really i need help in making out the equations of the motion of the magnet so as to visualize its motion.:cry:

source:British physics olymp. 1995:cool: a small slab of material is placed on a dish containing liquid nitrogen.The material is a superconductor at the temperature of liquid nitrogen.A small but strong magnet is moved near and placed over the slab.The magnet is seen to wobble but remains...
