If a billion children neaten their bedrooms, how much does the entropy of their toys and clothing decrease? Assume that they each have one hundred distinguishable items weighing 20gm, initially randomly placed in a bedroom with V=5m3 , and that they end up located in their place in a drawer with center-of-mass location accuracy of 1cm. For this exercise, assume that the internal entropies of the objects are unchanged in the process (atomic vibrations, folding entropy for socks, etc.) Compare this entropy change to that of contracting the air in a one liter balloon by 1% in volume.

i'm only doing this for the points : (

explanation:

i'm only doing this the points

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
