Water Flashcards
High boiling point
The temperature it takes for water to boil
High Heat Of Vaporization
The amount of heat it takes for water to evaporate
5400 cal/g
Hydrogen bonding
When water molecules are attracted to each other because of its polarity
Cohesion
Water molecules attracted to each other
Adhesion
Water molecules attracted to other substances
Capillary Action
Cohesion and adhesion together create a force that brings the water upward, getting the water from the ground to the plant
Ex: celery experiment
High surface tension
An Inward force or pull which tends to minimize the surface area of a liquid
Buffer
Help prevent student changes in pH- maintaining homeostasis (bicarbonate)
Water
Most important compound to life, makes up 70-95% of most organisms, universal solvent
Expansion on freezing
The water molecules expand which makes ice able to float on water
High specific heat
Water is able to absorb heat which causes the temperature to change slower in places near water.
Ex:
Virginia vs Missouri
