PHY 114: General Physics Laboratory Lab 1: Absorption of Nuclear Radiation 09/04/13 Abstract Nuclear physics was practiced to find the value of tau. After 8 trials of using a G-M counter and 8 different mass thicknesses of polyethylene‚ a graph was formed and tau was calculated to be 0.1931 cm^2/g‚ an error of 3.57% from the accepted value of 0.2 cm^2/g. Experiment was also used as an intro to using basic lab equipment‚ computer programs and calculating errors. With many different

Introduction The first law of thermodynamics states that the energy of the universe is constant. Heat is transferred when the atoms of one material vibrate and collide with the atoms of another material‚ thus transferring energy. For this reason‚ heats always travel from hot to cold objects and two objects will reach an equilibrium temperature. Materials and Methods 1. Oven 7. Test Tube 2. Pasco Temperature Probe 8.

DEFINITION OF HEAT TRANSFER | Heat transfer is energy in transit due to temperature difference . Whenever there exists a temperature difference in a medium or between media‚ heat transfer must occur. The basic requirement for heat transfer is the presence of temperature difference . There can be no net heat transfer between two mediums that are at the same temperature. The temperature difference is the driving force for heat transfer‚ just as the voltage difference is the driving force for electric

Sameera Raziuddin Latent Heat of Fusion April 11‚ 2011 Abstract: A calorimeter‚ water at room temperature‚ ice‚ and a Pasco GLS Explorer were used in combination with a known value of the latent heat of fusion to create and carry out an experiment to determine the mass of an unknown amount of ice. Using the formula for latent heat of fusion‚ the mass of the ice was calculated to be 45.76g. The error of the carried out experiment was calculated to be 20.06%. Introduction:

Civil Engineering Department‚ College of Engineering‚ Adamson University Abstract The purpose of this experiment is to determine the Latent Heat of Fusion of ice. In this experiment‚ the heat of fusion of ice will be determined by using the method of mixtures (Quantity of heat lost = Quantity of heat gained). Introduction When a substance changes phase

Heat of Neutralization Lab Objective: The objective of this lab was to measure‚ using a calorimeter‚ the energy changes accompanying neutralization reactions. Background: Chemical changes are always accompanied by a change in energy‚ typically as heat. If the reaction releases heat (ΔH < 0) then the reaction is exothermic. If the reaction absorbs heat (ΔH > 0) then the reaction is endothermic. The quantity of heat is measured experimentally by having the reaction take place in an insulated container called a

There were several possible sources of error that could be found throughout the lab. Some of the main errors as seen in question 7 that could have affected the results of the lab were the amount of water transferred with the hot metal‚ the metal cooling off as it was transferred from the calorimeter‚ the calorimeter lost heat to the surroundings as it was stirred
