See the two Related Questions to the left for a description of each one. They are different in both shape and function.Florence flasks have round bottoms and no gradations indicating volume. Erlenmeyer flasks are conical in shape and have gradations depicting volume on the side.
it's done to minimize the mixing of air into the filtered solution. By touching the stem to the collecting beaker, the solution flows into the beaker smoothly rather than splashing into it.

Many, if not all, desert areas are growing rather than shrinking through a process called desertification.
An alcohol lamp is one designed to burn alcohol rather than oil. The wick on it is typically but not always round rather than flat.
Back titrations are used when a reaction occurring in the conical flask can not be detected using an indicator such as phenolphthalein. So, after this titration has been performed, the 'excess' is then titrated with something that can be detected more easily using phenolphthalein etc.
The beaker is a glass container with an approxiamate capacity of 300ml. It is fragile and can break rather easily. There are markings on the beaker to allow the estimation of liquid volumes.

well there really is know difference its just a beaker is a thiker kind of glass rather than ordinary glass!! ps if that helped please reply back:-)
should informed consent be a process rather than a one time event
At the endpoint of an acidimetric titration there is no temperature change at all, so a thermometer won't indicate that.You'd better use the color change of a proper indicator when the pH changes at the end point. The only advantage is that it works well!
Richard, portrayed by Craig Roberts, is a teenager in Tracy Beaker Returns. His exact age is not specified in the series, but he is assumed to be in his mid-teens.
Melting is a physical process.
A natural process is a process that exists in nature rather than through human intervention. The forces involved in these processes are all products of nature.
