water properties

• Hydrophilic is the substances that dissolve in water
• Hydrophobic is the substances that do not dissolve in water
• An example of a Hydrophobic element is salt and sugar
• An example of a Hydrophobic element is oil
• Gas to Liquid - condensation
• Liquid to Solid - Freezing
• Gas to Solid - re-sublimation
• Solid to Liquid - Melting
• Liquid to Gas - evaporation
• Solid to gas - sublimation
• Cohesive is when the water molecules cling to each other
• Adhesive is when the water clings to other substances
• Water has a high heat capacity, or a great absorption of heat
• The amount of heat per unit mass (energy) needed to raise its temperature by 1 degrees is 4.2 joules per gram.
• Water has a high heat of vaporization
• Vaporization takes a lot of heat without its temperature
• Water expands when it freezes
• The spheres of hydration is the globe of water molecules that surrounds the exposed ions in hydration shells (water capsules).
• Water boils at 100 degrees/212 Fahrenheit
• Water freezes at 0 degrees/32 Fahrenheit
• Capillary action is the force of water moving up a vertical surface due to the pressure of the water. They are caused by cohesive and adhesive actions.
