Purpose: In this lab‚ we will heat up a metal rod and measure how much it expands. We will calculate its Coefficient of Linear Expansion‚ α‚ and prove the formula for thermal expansion‚ ΔL = αLiΔT. Also‚ we heat up a known volume of methyl alcohol and calculate its Coefficient of Volume Expansion‚ β‚ and prove the formula for volume expansion of a liquid ΔV = βViΔT. Equipment: Hollow Metal Rods of different metals‚ Steam Generator‚ Stand‚ Burner‚ Flexible Hoses‚ Motion Amplifier‚ Micrometer

圣经箴言 Proverbs of Solomon (Holy Bible) （勤劳）Lazy hands make a man poor‚ but diligent hands bring wealth. （勤劳）He who works his land will have abundant food‚ but he who chases fantasies lacks judgment. （勤劳）A sluggard does not plow in season; so at harvest time he looks but finds nothing. （）Dishonest money dwindles away‚ but he who gathers money little by little makes it grow. （少言）When words are many‚ sin is not absent‚ but he who holds his tongue is wise. （少言）A perverse

Determinant Expansion by Minors Also known as "Laplacian" determinant expansion by minors‚ expansion by minors is a technique for computing thedeterminant of a given square matrix . Although efficient for small matrices‚ techniques such as Gaussian elimination are much more efficient when the matrix size becomes large. Let denote the determinant of a matrix ‚ then where is a so-called minor of ‚ obtained by taking the determinant of with row and column "crossed out." For example‚ for a matrix

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

Ecclesiastes‚ and Proverbs In pondering on the ideas of wisdom found in Proverbs‚ Job‚ and Ecclesiastes‚ it is apparent that each of these wisdom writings are of significant importance in order to rightfully divide the Holy Scriptures. It seems that Proverbs‚ Job and Ecclesiastes praise wisdom and emphasize that true wisdom is to fear the Lord. However each of these books causes the reader to take a different perspective in interpreting wisdom literature. The book of Proverbs seems to be written

PROVERBS 1. A bad workman always blames his tools - It is not the tools we use which make us good‚ but rather how we employ them 2. Absence makes the heart grow fonder - When someone or something is faraway‚ you realise how much you love (or miss) them or it 3. A bird in the hand is worth two in the bush - It is preferable to have a small but certain advantage than a mere potential of a greater one 4. A cat may look at a king - A purported inferior has certain abilities‚ even in the presence of a
