Ch 13 - 3,2,1 writing

Liquid lab info:

__Purpose__ - 1. Study Archemedes Principle and prove that the mass (force) of the displaced water is equal to the Buoyant force. 2. Study Pascal's law and prove that the pressure is equal within a the liquid of a closed system

__Vocabulary__:Archemedes Principle, Buoyant force, Pascal's law

__Safety__ - Watch water faucet (high pressure), don't break the "thumb wars", clean up water messes

__Data tables__

__Calculations:__ Show work for all calcs done in data tables. (Title, formula and label each calculation) Pascal - Area, Pressure Arch - Buoyant force, Convert ml water to force of water.

__Questions:__ 1. Why do you think Archemedes decided that putting a crown in water was a good way to determine if it was gold? 2. What are the applications of Pascal's law? __Conclusion__ Restate purposes Results of both labs - (Did you prove the principles - give me results) Explain - Briefly explain the principles and tell why your results prove or disprove the principles.. Errors - Explain errors
