Chemistry 1010 Water

Bonding forces - attractive forces outside and between molecules From Yahoo Images

Solid - Strong attractive forces Liquid - varied attractive forces depending on compound Gas - No real attractive forces From Yahoo Images

Hydrogen Bond Attraction between molecules that have a Hydrogen connected to a F, O or N Very strong attractive force – breaks pipes in the winter Responsible for Surface Tension

Surface Tension

Dipole Force Attraction due to different electronegativities From Yahoo Images

Dispersion Force Produced from temporary dipoles From Yahoo Images

Boiling Point The temperature at which a liquids vapor pressure is equal to the atmospheric pressure

Vapor Pressure The partial pressure a gas exerts when in equilibrium with a liquid

How Does an Aerosol Can Work?

How Does a Pressure Cooker Work?

Heat and Matter Heat is used by matter to either increase its temperature change state While changing state, the temperature of a substance remains constant

Heating Curve for Water

How Does Changing States Make Hurricanes Form? Ice crystal nucleation starts at the top of the storm where temperature is lowest Because the conversion of water to ice gives off energy, it gets warmer at the top This heat causes the air to expand which causes wind to rise This rising wind increases and intensifies as a hurricane grows
