Beer Lambert Law Lab Purpose: The purpose of this lab is to prove the Beer Lambert Law experimentally. The various solutions used for this experiment are tap water mixed with food colouring‚ Introduction: The Beer Lambert Law shows the relation between absorbance of light of an object‚ the molar absorptivity‚ the concentration of the substance‚ and the distance the light travels. The Beer Lambert Law states that there is a linear relationship between the concentration of a solution and the

Induction and Faraday’s Thursday‚ October 25‚ 2012 Lab Report 6 Introduction and Faraday’s Law Objective: In this experiment‚ Faraday’s law of induction will be investigated. Theory: Faraday’s law of induction states the induced emf or voltage in a coil is proportional to the rate of change of magnetic flux through a coil‚ this is shown blew: Ƹ= -dɸ/dt Equation 6.1 The flux of the magnetic field is defined and the following: ɸ=BAcosΘ Equation 6.2

How The Scientist Discover The Interior Of The Earth Two ways that Scientist may study and find the interior of the Earth are with Meteorites and Magnetic Fields. The scientist may use meteorites to discover the interior of the Earth’s earlier solar system by studying the meteorites that arrived on the Earth. The scientist might use magnetic fields by the science advances which involves measuring the ocean and coming up with a hypothesis. Therefore‚ the meteorites and the magnetic fields all

Using Charles’ Law to Determine Absolute Zero Background Info It is noticed that in this lab‚ as the temperature of the water in the beaker is increased‚ the distance between the pipette and water plug increases. When this distance increases‚ the volume of trapped gas also increases. This relates to Charles’ Law as it shows that the volume of a gas is positively proportional to temperature. Theoretically‚ absolute zero is the lowest possible temperature‚ where all molecules have the least possible

Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion

The Ideal Gas Law Lab taught me that hydrogen is lighter than air‚ and can be ignited. The materials used for the experiment include 0.05 grams of magnesium‚ 1M H2SO4‚ water‚ a 100mL graduated cylinder‚ and a beaker. The hydrogen can be ignited with a match. First‚ the beaker is filled with water. The acid is then added to the graduated cylinder‚ with about ¾ inch left at the top‚ which is space for water. Afterward‚ the magnesium is added to the graduated cylinder‚ and it is inverted upside down
