Evaluation of a Gas Constant (Experiment 3)

Experiment 3: Evaluation of Gas Constant Purpose: The purpose of this lab is to demonstrate the ideal gas law under ordinary conditions. In this lab, the variables in the ideal gas law are known or can be found aside from the constant R. Thus, the R values can be found and relatively determine the relevancy…

Fire extinguisher

The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). A fire naturally occurs when the elements are present and combined in the right mixture and a fire…

Underwater welding

UNDERWATER WELDING INTRODUCTION The fact that electric arc could operate was known for over a 100 years. The first ever underwater welding was carried out by British Admiralty – Dockyard for sealing leaking ship rivets below the water line. Underwater welding is an important tool for underwater fabrication works. In 1946, special waterproof electrodes were…

A visit to Subir Raha Oil Museum at ONGC

As a part of the curriculum of the programs offered at UPES, the students of first semester MBA Energy Trading and MBA Oil & Gas were taken to Subir Raha Oil Museum, ONGC in Dehradun. Being the students of the petroleum industry, this visit gave us a rich and holistic picture about how oil it…

Scientific Investigation of the Peroxidase Enzyme & Temperature

Abstract:  In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the…

Case Vignettes in Acid-Base Balance

Choose three of the four vignettes and BRIEFLY answer the questions that follow. Normal Levels of Substances in the Arterial Blood: pH 7.40 + 0.05 pCO2 (partial pressure of carbon dioxide) 40 mm Hg pO2 (partial pressure of oxygen) 90 – 100 mm Hg Hemoglobin – O2 saturation 94 – 100 % [HCO3-] 24 meq…

Applying Thermal Expansion

Complete the following problems and exercises using complete sentences and showing all work where appropriate. 1. The temperature of the Sun’s interior is about 107 degrees. Does it matter whether this is degrees Celsius or kelvins? Defend your answer. No, it DOESN’t matter whether this is in degrees Celsius or kelvins, since the DIFFERENCE between…

Project Report on Effect of Impurities on the Boiling Point

Introduction Project Report Boiling Point and Freezing Point : Generally, on cooling a liquid its temperature falls gradually till it starts freezing. At this point the temperature remains constant till whole of the liquid changes into solid. “The fixed temperature at which a certain liquid freezes, is termed as its freezing point.” Freezing point of…

Sources of air pollution

Sources of air pollution refer to the various locations, activities or factors which are responsible for the releasing of pollutants in the atmosphere. These sources can be classified into two major categories which are: Anthropogenic sources (human activity) mostly related to burning different kinds of fuel • “Stationary Sources” as smoke stacks of power plants,…

Investigating the Effect of Temperature

The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents, for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to…
