Two very long parallel cylindrical channles are drilled through a very large block of material. The block is so large, that it can be considered infinitely large.

http://i24.tinypic.com/2mhu73s.jpg

The diameter of the channels is 16cm, and distance between theier centers is 20cm. One cylinder contains cold +10C water, and the other contains hot +50C water. Thermal conductivity of the material is 100 mW/cm/C.

How much heat flows from hot to cold water per 1cm length?

Because all matter is composed of atoms, the number of neutrons and protons in each atom must be equal.

TRUE or FALSE


I think TRUE for the second part but the first part with the "Because all matter is composed of atoms..." is confusing me!!! Is that WHY they are equal??? I hate these type of questions!!

Chemical bonds are necessary to keep atoms together although their negative outer surfaces create a weak attraction between the atoms.

TRUE or FALSE

I think it is TRUE but the after the distractor part- after the "although" - is what is making me think that it is FALSE.
