Surely the water level rises.... because.. ice has CAGE STRUCTURE of water molecules... and hence is in solid form.. but wehn it is heated.. it absorbs heat and then it melts.. what i mean to say is.. there is no change of amount of water when it melts... so when that happens... the ice-melted water and the pre-existing water mix up to raise the water level....
every1 is aware of the fact that global warming is a threat to our planet as it is resulting in the melting of polar ice caps. which is further causing rise in level of water in oceans. it is the reason that coastal regions r in danger of getting submerged. according 2 above criteria, when ice melts it results in rise of water level.
omgg!! what all answers But actually the level of water will remain constant!.It's is in't logical thinking which matters(and may be wrong) in such questions we need some theories to support our answer use the laws of floatation and get to the answer
suppose density of ice is i and water is w and mass of ice is m and volume be v1
we know that
there for v1=m/w (this is the volume due to the ice immered considering all effects of gravity and bouyancy)
after the ice melts to form water the new change in volume will be equal to mass of the ice/(density of wateer)
we can find that the initial and final changes are same and hence the level remains constant.
yes.. even though it is unbelievable that is physics .When i was young i too didn't believe and had even experimented with it and checked the level it is truee.. it is the laws of the nature. unbelievable hmm...
YES THE WATER LEVEL WILL REMAIN UNCHANGED
I agree my answer is wrong but then y is it that global warming is resulting in the rise of water level by melting of polar ice caps?
