Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side

Practical 3 Absorption Spectra and the Beer-Lambert Law INTRODUCTION Electromagnetic radiation can be described in terms of frequency (V) and wavelength (λ). Absorbance is the capacity of a substance to absorb radiation and transmittance (the fraction radiation at a specified wavelength that passes through a sample) is physical properties that all molecules have. The purpose of experiment one was to find the maximum absorbance (λmax) occurred for both bromophenol blue and methyl orange by

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter
