Abstract Molar volume is the volume that one mole of gas occupies when temperature and pressure are kept constant. The molar volume of a gas can be determined through evaluating how much gas is given off when the number of moles of the substance is known. To find the volume of gas that will be used to calculate the molar volume‚ the process of water displacement can be used. Reference Citation Cesa‚ J. (2002).

Trading Report Strategy Chosen Our strategy is consisted of two parts: when the market is neutral without obvious trends‚ we play like the role of market maker; on the contrary‚ we put our bet on the trend. At first‚ we calculate the weighted average quantity from the order book‚ says 1st to 4th layer‚ for both sides. If bid quantity is larger than 2.5 times of ask‚ we believe that bulls prevail and this trend will be continued in a phase. Thus we place a market order to buy‚ expecting to earn

Mechanical Waves Background Mechanical waves are waves which require a medium for propagation since energy is transferred via the motion of the medium. An example of a mechanical wave is sound. Transverse waves are waves which vibrate perpendicular to their direction of propagation. Surface water waves can be classified as a transverse wave. All electromagnetic waves are also examples of transverse waves. A longitudinal wave is a wave in which its particles vibrate parallel to their direction of

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

Experiment 8: LRC Circuit Aim The aim of this experiment is to measure and calculate the resonance frequency in different ways. Meanwhile‚ there is a requirement to use the apparatus proficiently. For the last part of the experiment‚ there is a demand to analyze the phenomenon and get a better understanding. Moreover‚ from this experiment‚ we can understand the principle of this experiment and learn some circuit knowledge. Background/ Theory In the experiment‚ in an LRC circuit‚ a resistor(R)

Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave‚ focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three

In general‚ the term “romance” sparks an image of powerful love‚ with half-naked women‚ but The Sound of Waves is actual romance‚ including two innocent youths who are new to how to love. Many morals and lessons are taught through this book through the actions and regrets of the characters. The perseverance during hard times‚ allows the characters to

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by
