Effects on the gas exchange of Chylamydomonas under controlled conditions Introduction: Is gas availability a limiting factor for algae growth this spring in the Louisiana State University (LSU) lake system? For three weeks, we observed the effect that changes in gas availability had on the rate of algae growth in the LSU Lake System to determine the optimal growth of Chlamydomonas. To study the effect that temperature had on the Chlamydomonas population, we compared three different environments:

Picture of molecule in the Solid, Liquid, Gas. Solid- is one of the fundamental states of matter (the others being liquid, gas,). It is characterized by structural rigidity and resistance to changes of shape or volume. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire volume available to it like a gas does. The atoms in a solid are tightly bound to each other, either in a regular geometric lattice (crystalline solids

molecular theory can be used to explain this phenomenon. As the temperature increases, the gas molecules move faster and are then able to escape from the liquid. The solubility of the gas, then, decreases. 2. Pressure The second factor, pressure, affects the solubility of a gas in a liquid but never of a solid dissolving in a liquid. When pressure is applied to a gas that is above the surface of a solvent, the gas will move into the solvent and occupy some of the spaces between the particles of the

where the required cylinder and packing lubricant is not compatible with the frame lubricant. These applications include high discharge pressure applications , or when the process gas conditions require an oil heavier than 40 weight, or a synthetic lubricant, such as when heavy hydrocarbons, wet gas or CO2 are present in the gas stream and would dilute a conventional lubricant. For applications requiring separate frame and cylinder/packing lubricant, the packager is required to provide a separate

Introduction Distillation is a procedure that has been used for many centuries as a separation technique to isolate liquids with different boiling points and vapor pressure. The idea of distillation generally involves the conversion of a solvent into a vapor then back to a solvent based on vapor pressure. The liquid with the lowest boiling point and highest vapor pressure would be collected first (Weldegirma,2017). There are various distillation methods, however the two methods utilize in this experiment

Distillation and Gas Chromatography Goal: The goal of today’s experiment is to collect three different fractions for each distillation by separating two different volatile solutions. Once the fractions are collected, we will record the boiling point range and perform a gas chromatography an original mixture along with the three different fractions that were collected. Significance: This lab is very important if someone needs to separate two different volatile solutions. They can do the simple

The data I will collect, is the moles and grams for each unknown compound, calculate the g/mol for the unknown compounds, and calculate the molar mass for the known compounds. To identify the unknown compounds, we first weighed all seven of the unknown bags. To find the weight of the unknown compound in the bag, we first subtracted the weight of the bag by first weighing an empty bag and pressing the zero button to zero out the weight of each for the seven unknown compounds. The mol of each unknown

Laboratory Questions: 1,2,3,4, and 5 1. Part A.3. Some of the cyclohexane solvent vaporized during the temperature versus time measurement. Will this loss of cyclohexane result in its freezing point being recorded as too high, too low, or unaffected? Explain. If some of the solvent has vaporized, the freezing point in part A.3. will not be affected because in that step the cyclohexane is still a pure substance without a solute to lower its freezing point (Beran, 2014). 2. Part A.3. The digital

What is more important, the cost of oil and gas, or the health of the human race? Horizontal Hydraulic Fracturing, more commonly known as “fracking” remains a relatively uncommon drilling technology. There was only one in fourteen wells drilled in the United States and Canada horizontally in 2002 (Gold). In 2012, six of every ten wells were horizontal. It is a process in which sand, water, and chemicals are used to blast open shale rock to release the gases that are trapped inside. After the vertical

is to find locations to catch the wind. Wind resource analysis and research will help identify the best places. Meteorological investigations and studies are performed looking for sites in which the average wind speed is appropriate for the wind turbines to be used. Wind speeds on average of 17+ miles per hour are ideal. Wind is typically monitored for six months to two years to corroborate the company’s research data
