What else can I help you with?
How can one accurately measure water clarity and what methods are used to do so?
Water clarity can be accurately measured using a device called a Secchi disk, which is a simple tool lowered into the water to determine the depth at which it becomes invisible. Another method is using a turbidity meter, which measures the amount of light scattered by particles in the water. These methods help scientists assess the transparency of water and monitor changes in water quality.
How do forensic scientists who study explosions determine what an explosive was made of?
Forensic scientists analyze residue, debris, and damage patterns at the explosion site to determine what explosive was used. They may use techniques like mass spectrometry, chromatography, and X-ray diffraction to identify chemical compounds present in the remnants. By comparing the findings to known explosive compositions, they can identify the specific type of explosive used.
What are the apparatus used to determine volumetric composition of water?
The apparatus used in laboratory to determine the volumetric composition of water is called Hofmann Voltameter. A Hofmann voltameter is an apparatus for electrolysing water, invented by August Wilhelm von Hofmann in 1866. It consists of three joined upright cylinders, usually glass.
How do you use the word isotopes in a sentence?
Scientists use isotopes to track the movement of water through the ecosystem.
How do you determine bound water and unbound water?
Bound water is water that is chemically bound to a substance, while unbound water is water physically trapped or held between particles. Bound water is typically not easily removed, requiring high temperatures to release, while unbound water can be removed with lower temperatures. Techniques such as thermogravimetric analysis can be used to determine the amount of bound and unbound water in a sample.
How did scientists determine that the Earth's mantle existed?
Scientists used detectors which determined the mantle existed. As well, scientists must hypothesize and theorize what cannot be readily seen, and make determinations based on the evidence that does exist.
Flotation is a method used by scientists to determine what of a particle of glass?
Density
Statistics are not used by scientists to do what?
Data Scientists can help determine whether or not that difference is significant enough to warrant increased attention.
DNA extraction is useful technique for scientists because it can be used?
To determine if people are related
What following is not a method used by scientists to determine the age of ancient remains?
Psychic readings.
Can salt water is used to determine the boiling point of water?
No, salt water cannot be used to accurately determine the boiling point of ultrapure water. Salt water boils at a slightly higher temperature than pure water; salt water can be used to determine the boiling point of salt water.
Used by scientists to make a prediction?
hypothesis
Why do you use organisms to determine water quality?
Organisms are used to determine water quality because they are sensitive to changes in their environment. By studying the types and abundance of organisms in a body of water, scientists can assess the health and ecological condition of that ecosystem. This information helps us understand the impact of human activities on water bodies and guide conservation efforts.
Scientists used measurements in the late 1800s to determine the classification and comparison of human races?
Anthropometry for A+ (:(:
What is the measurement of grains per gallon used to determine water hardness?
The measurement of grains per gallon is used to determine water hardness.
What is relative time used to determine?
Relative time is used to determine date on aging rocks. This helps scientists determine the period of time a rock originated.
When scientists make a prediction that can be tested what skill can be used?
hypothesizing?
