Q

list several properties of water and an example of each

A

solvent -dissolve in water
is also involved in chemical reactions

lubricant - major component of salvia, mucus, tears

buoyant - can float on it.
reduce stress In weight bearing joints, surrounds every cell in the body.

thin fluids- reduce viscosity of body fluids. ex: walking thru water vs walking thru syrup.
