is the concentration of a base in the buffer. is the concentration of a acid in the buffer. pKa is the dissociation constant of acid. What is buffer capacity Example? For example, 1 L of a solution that is 1.0 M in acetic acid and 1.0 M in sodium acetateRead More →
Preparing for your InBody Test Do not eat for 3-4 hours before testing. Do not exercise for 6-12 hours before testing. Ensure access to both feet with removable footwear and socks. Do not drink caffeine on the day of your test and be well hydrated. Do not shower or saunaRead More →
A manometer is a good example, as it uses the surface area and weight of a column of liquid to both measure and indicate pressure. Likewise, the widely used Bourdon gauge is a mechanical device, which both measures and indicates and is probably the best known type of gauge. WhatRead More →
To create an inkblot creature, I invited guests to put a few drops of each color on their paper, fold it in half along a center crease, then press and rub all around the folded paper. When they opened it back up, the paint had squished and spread into anRead More →
Testing the DC electrical current is a basic measurement, but not many tools can do it right. Using a power clamp meter with an easy-to-read display and simple settings will assist you better in reading AC/DC current. How accurate are DC clamp meters? Accuracy. Current measurements are accurate to withinRead More →
As a larger unit of measurement, GHZ is 1000 times greater than MHz. Conversely, 1 MHz is 1000 times smaller than 1 unit of GHz. Does MHz matter in RAM? RAM frequency is measured in MHz and usually immediately follows the DDR version in the RAM spec. … This isRead More →
The reorganisation energy is defined as the energy required to distort the reactant and its associated solvent molecules, from their relaxed nuclear configurations, to the relaxed nuclear configurations of the product and its associated solvent molecules. What is solvent reorganization energy? The solvent reorganization energy, λ, is the energy requiredRead More →
Ceilometers are used for meteorology and aviation mostly. Cloud data is reported to flight crews and cloud ceiling status is monitored continuously at airports. Some ceilometers are capable of measuring cloud layers as high as 30,000 feet. They are also able to measure multiple cloud layers to this height. WhatRead More →
Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m–3). It is therefore a relative quantity with no units. What does the specific gravity actually measure? It measures theRead More →
Plug the information you have obtained into the formula for viscosity: viscosity = /9v where ps is the density of the sphere, pl is the density of the liquid, g is acceleration due to gravity (a fixed value of 9.8 m/s2), a is the radius of the sphere, and vRead More →
