Experiment 1: Thermal Linear Expansion Abstract: The thermal linear expansion of copper and aluminum is the focus of this experiment where the two metals have a tendency to expand their length in response to the change of temperature. Each metals have their own coefficient of linear expansion which describes how the size of an object changes with a change in temperature while the pressure is held constant. We ’re able to determine the theoretical coefficient of linear expansion of the two metals by substituting

Page 1 of 4 Expansion Devices I. Introduction Expansion devices are basic components of a refrigeration system which carry out two major purposes: (1) the pressure reduction from the condenser to evaporator pressure and (2) the regulation of refrigerant flow into the evaporator. These expansion devices can be generally classified into two types which are namely the fixed opening type (flow area is fixed) and the variable opening type (flow area changes correspondingly with a change in mass

experienced a marked change in national unity. Territorial expansion had a large effect on national unity in this period. Territorial Expansion was among the great subject of debates during the period 1800-1855. These debates discuss arguments in favor or non-favor of U.S. Expansion. The arguments express concerns‚ fears and advantages the nation will experience by the consequences of expansion. Documents A‚ C‚ D‚ H and I are against territorial expansion.

European Integration: Where are the limits of European integration? Why? Unifying Europe has long been a dream of many political thinkers and leaders‚ even non-European ones‚ such as Winston Churchill (1946) who dreamed of the establishment of “United States of Europe” in order to avoid wars driven by nationalist ambitions. However‚ promising Europeans with happiness and economic prosperity for everyone would not be sufficient to trigger political cooperation and goodwill of the European countries
