Wind Chill Temperature Index - National Weather Service

how cold air feels on human skin. The former index used by the United States and Canada was based on 1945 research of Antarctic explorers Siple ... As a result, the previous wind chill index underestimated the time to freezing and overestimated the chilling effect of the wind. The current index is based on heat loss from exposed skin and was ...

Phase diagram of water - Columbia University

Water has a high specific heat index. It takes much more heat to raise the temperature of a volume of water than the same volume of air. This is why water is used as a coolant. This property of water is a major determinant of global climates and rates of global climate change - changes in temperatures are gradual - “lake” effects

States of Matter - NASA

Most of Earth's water (97%) is in the ocean. Seawater has unique properties: it is saline, its freezing point is slightly lower than fresh water, its density is slightly higher, its electrical conductivity is much higher, and it is slightly basic. Circulation in the ocean depends in part on differences in density of the water. Water with more
