This report will cover the adaptations relating to gas exchange in insects‚ fish and mammals. These all have different gas exchange systems but work in similar ways. All the animals studied have the same characteristics in order for them to be able to work properly. Overview The gas exchange system is the process in which oxygen enters the cells of many living animals. Some factors that affect how efficient a gas exchange system is are things such as the distance that the molecules have to go before

EXERCISE 10 Demonstrating Gas Laws Lab Group II Introduction The three gas laws discover the relationship of pressure‚ temperature‚ volume‚ and amount of gas. Boyle’s Law tells us that the volume of gas increases as the pressure decreases. Charles’ Law tells us that the volume of gas increases as the temperature increases. A third gas law may be derived as a corollary to Boyle’s and Charles’ laws. According to Gay-Lussac’s Law‚ for a given amount of gas held at constant volume‚ the pressure

A safety audit for the gas-solid fluidization experiment was conducted. The following safety concerns were found when performing the audit: operating beyond the operating limits‚ spillage of the beads‚ risk of head injury from bending over to change the beads in the apparatus or from the low bar‚ and congestion of the workspace. One of the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic

Lab 2: Reaction Order and Rate Laws Khadijah Maraheel Location: My apartment September 27th-28th 2017 Course Number: Chem112 Abstract: The purpose of this lab is to find the rate law of the reactants and the reactions order. My beginning thought was I would find whole numbers but that would be to easy. My answers were all with decimals. I found that my rate law Is k (HCl)1.36 (Na2S2O3)0.84. I was expecting the solution to change color but I never thought it would turn

2014 Empirical Analysis of Mendel’s Laws Objective: To determine if Mendel’s law of segregation and independent assortment genetic principle’s hold true by observing the genotypes of both the F1 and F2 generation of Drosophilia Melanogaster flies and applying the Chi Square analysis to the F2 offspring to see if the our results fall inside or outside statistical variation. Methods: This experiment was carried out over a five-week process. Each lab bench crossed two parental generations:

Objective: The purpose of this lab is to demonstrate that there is a linear relationship between the number of molecules that can absorb light present in a solution and the amount of light absorbed by a solution. This lab should prove that Beer’s law and the equation A=a x b x c‚ is a linear relationship. Procedure: The only deviations in the lab procedure was that the stock solution was made before arrival to the lab with 0.570 g of KMnO4 in 0.500 L. The diluted solutions and the

Hess’s Law and the Molar Enthalpy of Combustion for Magnesium Purpose: The purpose of the lab ultimately is to find the molar enthalpy of magnesium. This is done by finding the enthalpy changes of reactions (2) and (3). The enthalpy changes of reactions (2) and (3) along with the enthalpy change given for reaction (4) can be used to arrive at a value of the molar enthalpy of combustion of magnesium by using Hess’s Law. Hypothesis: By using Hess’s law to calculate the molar enthalpy of combustion

PHYS113 Lab1: Coulomb’s Law ABSTRACT Performing this experimentation will allow one to investigate the relationship quantitative relationship between the electrostatic force and the distance between charged objects. First a simply observation was made of the electrical forces on two pieces of tape taking note of their attraction and repulsion. This same phenomenon was observed in the experimentation of two charged spheres. Furthermore the we used this experimentation to determine the

2/28/2013 Introduction: Hess ’s law is a terminology in chemistry named after Germain Hess‚ a Swiss-born Russian chemist and physician who published it in 1840. The law states that the total enthalpy change during the complete course of a reaction is the same whether the reaction is made in one step or in several steps. Enthalpy cannot be directly measured‚ but rather the change in enthalpy. Enthalpy is described as the change in kinetic and thermal energy. Hess’s law states that the enthalpy change
