The Law of Conservation of Energy states that energy can neither be created nor destroyed, but it does have the ability to change forms. Take for example an object of mass ( m ) that has been raised to some arbitrary height ( h ). The work ( W ) done on the object isContinue reading “FLUIDS: Torricelli’s Theorem and the Conservation of Energy”

SOLIDS: Determining the Mass of a Golden Sphere
Q: Gold has an atomic mass of 197 amu. If a golden sphere has a diameter of 0.10 m, how many atoms does it contain? A: In order to determine what volume ( V ) is occupied by the sphere, we must obtain a value for the sphere’s radius ( r ). Fortunately, the radiusContinue reading “SOLIDS: Determining the Mass of a Golden Sphere”
GAS LAWS: Boltzmann’s Constant
In previous circumstances, a known quantity of an ideal gas in moles ( n ) was shown to influence a volume of space in accordance with the Ideal Gas Law ( PV = nRT ). It is useful, however, to be able to determine the number of molecules ( N ) of a gas thatContinue reading “GAS LAWS: Boltzmann’s Constant”
