First of all, there's our social supports, our communities, our families, the people who are important to us, the organisations we work for, so one way we can look at resilience is to measure that – the amount of social support available to us. Another way to think about resilience is...

So, to identify ethanol in a sample, you have to look at the wavelengths of the bonds in ethanol (C-O, O-H, C-H, C-C) and measure the absorption of IR light. The absorbed wavelengths help to identify the substance as ethanol, and the amount of IR absorption tells you how much ...
It's important to remember that temperature and heat are not the same thing. **Temperatureis a measure of how hot something is, measured in degrees Celsius or degrees Fahrenheit, whileheat** is a measure of the thermal energy contained in an object measured in joules. When heat energy trans...
Step 2: Figure out how much of your allowance you want to save and how much you want to spend. Put aside a 5 for your long-term goals. Take two envelopes. Write "spend" on one and "save...
The relative amounts of these materials can be determined by titration with acids. The base number is a measure of the amount of basic substance in the oil, always under the test conditions. It is sometimes used as a measure of lubricant degradation in service. However, any condemning ...
Parts per million or PPM is a dimensionless measure of the concentration of one substance mixed in with another. For example, the amount of lead in a sample of water, or the amount of CO2in the atmosphere. It's essentially like a percentage, which you could analogously refer to as "parts...
How to measure the pH value of a solution? pH indicator.A pH indicator is a weak acid in the form of a natural dye, which indicates the concentration of H+ (\(H_3O^+\)) ions in the solution through a color change.The pH value is determined by the negative logarithm of that conce...
Measure the volume of the homogeneous mixture. If it is a liquid, pour some into a graduated cylinder. Read and record the volume. If the mixture is solid, pour some water into a beaker or graduated cylinder, read the volume and then place the solid in the water. Make sure the solid ...
