Date: 25th November‚ 2011 Aim: To show that when Hot and Cold water are mixed‚ heat lost by hot water is equal to heat gained by cold water. Theory: This Lab is done to demonstrate “the Law of Conservation of Energy”‚ which implies: - “the heat lost by one (1) substance must be equal to the heat gained by another substance within the system”. Apparatus: Two (2) similar Calorimeters: a Thermometer: a Measuring Cylinder: a Bunsen burner: a Tripod: an Asbestos Gauze Cork Mat. Procedure:

Ohm’s Law Lab Report Number Three Quyama T. Wheeler @02669651 Partner: Munah Kaye Amber Frazier Objective: To demonstrate Ohm’s law and to determine the resistance of a given resistor. Theory: Ohm’s law is the assertion that the current through a device is always directly proportional to the potential difference applied to the device. Electric current is the moving of charges from a higher potential to a lower potential. Wires of different material (a copper wire versus a silver wire‚ for

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

Purpose and Method: The purpose of this experiment was to understand Boyle’s Law. In the experiment the pressure in the system under constant temperature and mass was used to confirm if the laws are true. Boyles law relates pressure and volume while all other factors are consistent and states: for a fixed amount of gas kept at constant temp‚ the product of the pressure of the gas and its volume will remain constant if either quantity is changed‚ or where k is constant. The experiment consisted

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
