Physical • Liquid, Gas, and Solid • Freezes at 32° Fahrenheit (F) and boils at 212°F • pH of 7 • Cohesive • The stickiest of the non-metallic liquids • Pure water doesn’t conduct electricity • High specific heat index • Absorbs a lot of heat before it evaporates • High surface tension • High density
Chemical • Universal solvent • Dissolves more substances than other liquids • Important: • takes with it valuable chemicals, minerals, and nutrients (especially in our bodies) • Why: • “Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.” • Attracted to many different types of molecules • BAD: • Pollution is easily attracted and distributed by it.
