Why does ice float? It is denser than water and surface tension helps it. Because the hydrogen bonds start to spread apart far enough to make it less dense than water when it cools.

Why is water's high heat capacity (Specific Heat) important? It helps stop sweating. It regulates the temperature of not only human bodies but land masses.
It regulates the temperature of not only human bodies but land masses.
What is the octet rule? Tells how many protons every atom is trying to get during bonding. Refers to the maximum number of babies that can naturally fit inside a human uterus. "Octomom." It tells that low atomic number atoms generally want 8 electrons in their valence shells-except for H and He, which only can fill their single shells with 2 electrons. If you're going to start up a new singing group (like Pentatonix), you need at least 8 good singers.
