I’m guessing the answer is AX (the first one) sorry if I am wrong tho
(1) The melting of a crystalline solid is best depicted by the second graph. This is because, the second graph shows a horizontal line which means that for a while there was no change in temperature. This zone is the latent heat of fusion.
(2) The first graph shows the graph of a solid that is just heated but does not experience phase change. However, the second graph shows a solid that changes phase (from crystal/solid to liquid).
<span>In a chemical change, the molecular structure of a substance changes. I think this is right. I hope this helps.</span>
True, wetlands help to prevent flooding.
The question doesn't really make sense, but I am pretty sure the answer is atomic number.
