Purpose: This lab taught procedures for determining heat of capacity of a calorimeter and measuring enthalpy of change for three reactions. It also enforced methods of analyzing data obtained through experimentation and calculating enthalpy. These procedures are used in the branch of thermodynamics known as thermochemistry which is the study of energy changes that accompany chemical reactions. Concepts from this lab can be used to determine the potential energy of a chemical reaction. Much of the energy people depend on comes from chemical reactions. For example, energy can be obtained by burning fuel, metabolizing of food or discharging a batter.…
This course will incorporate the following teaching/learning methods: Primarily lectures, class discussion, and a group project. Numerical work and quantitative problem-solving are integral to…
1. Determine the average initial temperature for each trial by averaging the initial temperature of the NCI and the NaOH solution before mixing. Record as Average Ti before mixing in Data Table 1.…

To look at how the pressure drop changes when the average velocity is altered in a circular pipe and to plot a graph of Friction Factor versus Reynolds Number. Another aim is to examine the shift from laminar flow to turbulent flow.…
When watching tennis match or any other sport who of thought science played a big part? Science is involved in many things; we just don’t see it. It’s much entertaining to watch a match then to learn from it. The way we look at science is the use of chemicals, explosions, experiments, etc. What we don’t really see is how science is related to any sport. The use of these science laws plays a big part in the way sports are played. Newtown’s laws of motion and the laws of thermodynamics set great examples in a tennis match to help us gain more knowledge in how they’re being used on earth.…

Cv = 3/2 R = "heat" required to change the temp of 1 mol of gas by 1K at constant…
The first example is oscillating a pendulum, which is categorized in the law of motion due to the object remaining in that state unless an external force is applied. The second example stating cooling food and drinks in a refrigerator is categorized in the laws of Thermodynamics due to thermalization. The third example of using the coffeemaker can be a combination of both laws due to moving touching to coffeemaker to make create an action is Law of Motion, however, if we were heating the coffee to change the temperature, then this becomes law of Thermodynamics. The forth example is heating dinner which is Thermodynamics due to using temperature as our factor. The next example is heading a football, which uses the second law of motion, which is when velocities change when force is applied. The next example of throwing a baseball is the same concept, which is law of motion due to applying force. The last example of slamming on your brakes is the third law of motion, which is for every action there is an equal or opposite reaction.…
Energy is encountered in many forms, such as mechanical, chemical (food and fuel), electrical, nuclear, heat, and radiant (light). Energy has the ability to bring about change or to do work. Thermodynamics is the study of energy. The field of thermodynamics studies the behavior of energy flow in natural systems. These studies have rendered two laws of thermodynamics.…
Prompt #1: Does it matter that you can not really touch anything? How does this make you feel? If you could touch something, what would you touch? How do you think it would feel?…
The purpose of this experiment is to test kinetic theory by running several reactions and…
The two studies by Dehaene-Lambertz, Dehaene, and Hertz-Pannier (2002), as well as, Homae, Watanabe, and Taga (2014) will be compared. The studies measure the perception of speech sounds in the infant brain using functional magnetic resonance imaging (fMRI). Each set of researchers collected data from young infants around 3 months. Different qualities of sound were presented to the infants in order to measure the activation of certain structures in the brain. The hemodynamic responses to different qualities of sound allowed the two sets of researchers to determine the general functions of the different areas of the infant brain while perceiving speech. The presentation of speech sounds activated the left temporal lobe and the frontal regions.…
[BLANK_AUDIO]. Welcome back. So last time we talked about work transfer as a form of energy transfer across the system boundary. Now there are a few key points we need to remember.…
