- A low-precision gravimetric titration can achieve 10,000.the same. reproducibility as a titration with a 50 mL volumetric buret. It requires less reagent quantities, it is faster and less. complicated titration for the students and the teacher, and the equipment. is far less expensive.

Tensile Properties Poisson's ratio is sometimes also reffered to as the ratio of the absolute values of lateral and axial strain. This ratio, like strain, is unitless since both strains are unitless. For stresses within the elastic range, this ratio is approximately constant.f volume is constant, a corresponding lateral contraction or expansion must occur. This lateral change will bear a fixed relationship to the axial strain. The relationship, or ratio, of lateral to axial strain is called Poisson's ratio after the name of its discoverer.

Compressible flow Compressible flow (gas dynamics) is the branch of fluid mechanics that deals with flows having significant changes in fluid density. Gases, mostly, display such behaviour. While all flows are compressible, flows are usually treated as being incompressible when the Mach number (the ratio of the speed of the flow to the speed of sound) is less than 0.3 (since the density change due to velocity is about 5% in that case).

- WEIGHING BY DIFFERENCE. (From Dr. David Chesney) Weighing by difference is the most accurate method to measure quantitatively the mass. of a solid sample. This procedure involves repetitive weighings of a weighing bottle. containing a quantity of solid reagent. As the solid is removed to another vessel, the. mass of the weighing bottle contents decreases. Upon reweighing, a lower mass is found. The difference in the two masses represents the mass of solid reagent transferred to the. vessel. Hence, the phrase weighing by difference.

Question: The kinetic theory of gases states that the kinetic energy of a gas is directly proportional to t... Since the square of velocity is always positive, this measure does not average to zero over the entire gas. A third measure is the root-mean-square (rms) speed,Vrms , equal to the square root of (V^2)avg. The rms speed is a good approximation of the the typical speed of the molecules in a gas. This histogram (Figure 1) shows a theoretical distribution of speeds of molecules in a sample of nitrogen () gas.

Weight The steeper the bank, the greater the g-forces. This top-fuel dragster can accelerate from zero to 160 kilometres per hour (99 mph) in 0.86 seconds. This is a horizontal acceleration of 5.3 g. Combined with the vertical g-force in the stationary case the Pythagorean theorem yields a g force of 5.4 g. The g-force (with g from gravitational) is a measurement of the type of acceleration that causes a perception of weight.

LabBench Activity Types of Solutions Based on Solute Concentration The terms hypotonic, hypertonic, and isotonic are used to compare solutions relative to their solute concentrations. In the illustration, the solution in the bag contains less solute than the solution in the beaker. The solution in the bag is hypotonic (lower solute concentration) to the solution in the beaker. The solution in the beaker is hypertonic (higher solute concentration) to the one in the bag. Water will move from the hypotonic solution into the hypertonic solution. In this illustration the two solutions are equal in their solute concentrations.

Lab Report = Surface area to volume ratio effect on diffusion The experiment results seen on the graph (trend line) show that the bigger is the surface area to volume ratio, the bigger is the percentage volume of diffusion, so the rate of diffusion of pigment from the agar cube. Looking at the data we can notice that smaller cubes (of smaller volume) have bigger SA:V.

Which method, gravimetric analysis or volumetric analysis is more reliable and why? In most gravimetric measurements, you WEIGH a final product, which either IS the compound of interest, or is stoichiometrically related to it. 2. Gravimetric methods are less sensitive to temperature than volumetric methods. 3. While BOTH types of methods are subject to sample loss, gravimetic methods are less so. (Note: This is less true if the analyst is a clutz.

Difference Between Volume Flow and Mass Flow So what’s the difference? Looking at the fundamental vacuum relationship Q=SP, we have. Gas Load = Pumping Speed x Pressure, or Mass Flow = Volume Flow x Pressure. Volume Flow. Volume flow is most commonly used to describe and quantify pumping speeds. Most commercial sales literature for pumps will provide a pumping speed vs. pressure curve. The figure shows some examples.

- Specific energy, energy density. Specific energy, or gravimetric energy density, defines battery capacity in weight (Wh/kg); energy density, or volumetric energy density, reflects volume in liters (Wh/l). Products requiring long runtimes at moderate load are optimized for high specific energy; the ability to deliver high current loads can be ignored.

10.8 Molecular Effusion and Diffusion Calculate the ratio of the effusion rates of N2 and O2, rN2/rO2. Diffusion and Mean Free Path. Diffusion, like effusion, is faster for light molecules than for heavy ones. In fact, the relative rates of diffusion of two gases under identical experimental conditions is approximated by Graham's law, Equation 10.23.

- If gas is compressed, then cooled (in an intercooler), then compressed again, the process is called polytropic compression (polytropic means 'many stages'). Purpose of polytropic compression. In order to make compression more efficient it needs to be as close as possible to isothermal.

Benchmarking the new AWS M3 instances with Redis As expected, fork time using the m3.2xlarge instance is significant lower than fork time on an m2.2xlarge instance, as it uses Xen’s full virtualization mode (HVM). Similar low fork time results are also seen over AWS Cluster Compute instances (see more info here), but at a much higher instance cost. Throughput and Latency We compared the throughput and the latency of a single shard Redis on both instances, and this is what we got: Our insight:

Quantitative analysis (chemistry) Gravimetric analysis yields more accurate data about the composition of a sample than volumetric analysis but also takes more time to perform in the laboratory. Volumetric analysis, on the other hand, doesn't take that much time and can produce satisfactory results.

- Oil is usually more viscous than water, yet oil is less dense and floats on top of water. If a fluid is heated, it tends to become. less viscous, and if cooled, it tends to become. more viscous. The colder the temperature, the. more viscous the fluid becomes, hence the. saying “slower than molasses in January”.

- Although blender technology was originally developed to using volumetric principles, in recent years, higher precision gravimetric blenders have emerged as superior, simpler to use, with more model available and comparable in cost to lower accuracy volumetric models. Comparisons between the two are: Operation:

- Both have similar kinetics, meaning the mechanism by which they work is similar. In facilitated diffusion, a ligand moves through a membrane through a channel. If the concent … ration of ligand increases, the rate of diffusion increases until the channel becomes saturated and can work no faster.

- Intermolecular forces are stronger in liquids than in gases. A gas is the physical state characterized by the complete dominance of kinetic energy (disruptive forces) over pot … ential energy (cohesive forces). Thus, gas particles move independently of one another. On the other hand, a liquid is the physical state characterized by potential energy (cohesive forces) and kinetic energy (disruptive forces) of about the same magnitude.

Gravimetric Analysis Gravimetric analysis or gravimetric determination is a method of quantitative analysis in analytical chemistry in which any element or compound gets precipitated from its solution by using suitable reagent. The precipitate obtained from the reagent can be collected by filtration.

science buzz It's one of the givens of kinetic molecular theory. It explains why hydrogen gas diffuses faster than carbon dioxide. Thus there is a greater probability that a lighter molecule like hydrogen will be able to cross a given transient empty space faster than a heavier one before the gap, so to speak, closes up.
