wasser mit metal calcium high melting point

Why does water have a high melting and boiling point

It’s due to a phenomenon known as hydrogen bonding, which sees the molecules in ice & liquid water attracted to each other. The constituent atoms in water (hydrogen and oxygen) have weak partial positive (H) & negative (O) charges on them, and these charges lead to electrostatic forces of attraction existing between neighbouring molecules:

Eucrites contain a relatively high ammount of calcium-bearing minerals such as plagioclase and augite. When mixed with free metal that has been oxidized to magnetite in the fusion process, these minerals produce a black, glossy fusion rind that often displays striking flow features..
