Document Summary

Chemical exchanges with the atmosphere, coastal zones, seafloor.

Polar molecule with a50 degree bond angle between oxygen and 2 hydrogen atoms. Held together by covalent bonds- sharing electrons. High surface tension: cohesion between water molecules and adhesion to other surfaces. High heat capacity: 1 cal/g/1 degree celsius- takes 1 cal of heat to heat 1 g of water by 1 degree celsius. Granite has . 2 cal/g/1 degree celsius- needs less heat. Takes a long time for water to warm up and cool down. Max change in temp on land: 250 degrees f (140 degrees c) Max change in temp in ocean: 60 degrees f (34 degrees c) High latent heats of vaporization and fusion. Density in solid phase < density of liquid phase \ Liquid ammonia has a higher specific heat than pure water.
