Document Summary
Organisms require water more than any other substance. Most cells are surrounded by water, and themselves are about 70%-95% water. To date, nearly 600 planets have been found outside our solar system; some contain water. In our solar system, mars has been found to have water. Responsible for the transport of water against gravity in plants(capillary action) Surface tension- a measure of how hard it is to break the surface of a liquid . related to cohesion. Water absorbs heat from warmer air and releases stored heat to cooler air. Water can absorb or release a large amount of heat with only a slight change in its own temperature. Temperature= measures the average intensity of heat due. Calorie- is the amount of heat required to raise the temperature of 1g of water by 1 c. The joule is another unit of energy where 1j=. 239 cal, or 1cal=4. 184 j.
