Lab Report : The Effect Of Moisture Concentration On The Dry Density Relationship

The objective of this experiment was to learn how water displacement affected density. Another objective was to identify the metals used in our experiments. We used a variety of different metals to test their correlation and to find out if it was negative or positive. I did not expect to learn much from this experiment as we had already discussed density in class and learned that water displacement is basically volume so as it increased the density would have decreased had we used metals of the same mass.

The purpose of this lab is to test substances and to determine the physical and chemical properties of substances.

1. What was the purpose of using water as a sample in some of the tests performed in the lab? (2 points) to have a control.

I will measure the soil PH in 5 different places to get an accurate and reliable results.

Read in your lab manual about the following agar mediums: Blood Agar (pg 168), EMB Agar (pg 170), Mannitol Salt Agar (MSA)(pg 172) ), MacConkey Agar (pg 174), and PEA Agar (pg 176) to answer the following:

13. If a soil has a moisture tension of 0.15 bars and the salinity of the soil water is 1.86 dS/m, what is the total tension experienced by the plant roots? That is, what is the sum of the moisture tension and the osmotic (due to salinity) tension?

In Measuring and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid, gas or

The materials that were used to carry out the experiments on the water samples were ten testing kits. We ran 10 tests on all

The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water. Drops were carefully counted and emptied into the empty plastic 25 mL graduated cylinder until the water level reached 1 mL. The number of drops in 1 mL was recorded into data table 3. The thin-stemmed pipet had a total volume of 4 mL and that was also recorded into data table 3.

Moisture Scavengers controls the effects of humidity in the application of two-component. The moisture scavenger must be rapidly react with water to avoid carbon dioxide bubbles generation or any undesired byproducts, so, due to the rabid hydrolysis of the Vinyltrimethoxy silane in the acidic water [14], it can be used as moisture scavenger in polyurethane coatings, where the hydrolysis products are 3 moles of methanol and on mole of vinyl silanol (Scheme 1). The hydrolysis mechanism involves the protonation of the leaving Methoxy group followed by a bimolecular SN2-type displacement of the leaving group by water. The methanol will volatile along with the other solvents from the coating surface but the formed vinyl silanol will remain in the

In planning for the construction of the Baroga Building, I recalled my experience in designing another building in that neighborhood for Sage College in 1952, which required that I become versed in the unique sub-soil characteristics there. Based on test borings for that first project, I became aware

During this experiment, many trends and patterns were found and noticed. The first trend occurred early in the experiment, this is the trend that the solution with sucrose started out faster that the solution with sodium chloride and this can be seen in how it is faster in reaching the sound of crackling. However, further along the experiment the solution with sodium chloride starts overtaking the solution with sucrose resulting in a faster evaporation time. The next trend, that can be seen in my graph and tables is how the independent variables take less than 3 minutes in transforming from one change to the other, e.g. from small bubbles to big bubbles. Adding to this, if we compare the averages of the same amount of independent variables,

Believe it or not, the soil around your home in New Braunfels will have an impact on its foundation. You have three key factors that will determine the amount of pressure. First, it depends on the types of soils that you have around your foundation. Second, it depends on the moisture of the soil. Finally, the pressure will depend upon how deep the foundation has been dug. A deeper foundation tends to be better for areas with expansive soils because it reduce the pressure. Oshan Foundation Solutions has helped countless people over the years struggling with a crumbling foundation. We are professionals who understand the value of your time, which is why when we do an estimate, we will also give you a deadline.

Analysis of representative soil samples will also be undertaken to characterise different soil material, for example, pH, particle size, organic matter, potential contaminants and so on.

1. If you are the sort of person who often find yourself with sweaty hands while playing basketball, Point 3 Basketball's basketball shorts might be just what you need. All their shorts are created with DRYV Moisture Control Technology, a technology patented by Point 3 Basketball, so no one else can use it. Basically, the shorts include a built-in towel, which absorbs the sweat from your hands, allowing you to keep your hands dry while playing basketball.
