Properties of Water Flashcards
(8 cards)
Solvent - water is capable of…
dissolving other ionic and polar molecules (as water travels through water cycle, it takes many valuable nutrients along with it)
Each water molecule can form how many H bonds with other molecules?
4
Hydrogen Bonds cause…
Adhesion and cohesion
Cohesion causes…
Surface tension (allows water striders to walk on water)
Adhesion causes…
Capillary action (fluid transport in plants)
Water is less dense as a solid than a liquid because…
ice molecules form crystalline structure that pushes molecules farther apart (allows life to continue to thrive under ice because ice floats and insulates)
High heat of vaporization
Allows evaporative cooling (evaporating sweat absorbs excess body heat)
High specific heat (heat capacity)
Helps regulate temp of environment (bodies of water maintain relatively constant temp)
