At 85 degrees F they only lose about 5 percent per year, but at 100 degrees they lose 25 percent per year. So if you live in a very hot climate or are storing your batteries in a very hot location, it may be worthwhile for you to store your alkaline batteries in a refrigerator instead.
What is a Diamond? A diamond is a crystal which is composed of the element, carbon. In nature, diamond crystals display a crystal habit, but often the crystal shape has been rounded or abraided during emplacement. Diamonds typically occur in a rock called Kimberlite and in related cousins (Lamproite).
Diamond is the ultimate gemstone, having few weaknesses and many strengths. It is well known that Diamond is the hardest substance found in nature, but few people realize that Diamond is four times harder than the next hardest natural mineral, corundum (sapphire and ruby).But even as hard as it is, it is not impervious. Diamond is transparent, Graphite is opaque. 2  Diamond crystallizes in the Isometric system and graphite crystallizes in the hexagonal system. 3  Somewhat of a surprise is that at surface temperatures and pressures, Graphite is the stable form of carbon.
