When looking at a graduated cylinder, what is the meniscus and why is it important?

1 answer:

6 0

When reading a graduated cylinder, a proper way to do it is to read at the level of the lower or upper meniscus. It is the curve formed at the upper part of a particular liquid that is close the surface of its container. This is caused by the surface tension. It can be in a concave or convex form depending on the characteristics of the liquid. It is important especially in performing laboratory experiments as it indicates the true level of the liquid in the container. When reading from apparatus, the lower meniscus or the upper meniscus is taken as the correct reading otherwise you would record a wrong data.

Long-term use of sedatives can cause side effects such as Psychiatric disorders such as anxiety.

It has been suggested that treating depression and anxiety with sedatives/hypnotics, especially benzodiazepines, may reduce the risk in the first few weeks. Sedatives/hypnotics also have inhibitory and disinhibitory properties, but these may increase the risk

Ashley can state her findings as statistically significant, which means that the findings are real and cannot be explained solely by chance or random factors.

Higher assurance or confidence in the results is implied by high statistical significance.
