Why is a beaker more acurrate to use when measuring the evaporation over a period of time of a liquid instead of an Erlenmayer flask???
I don't know that it is. It depends upon the size of the Erlenmeyer flask, the beaker, how much water is in the flask/beaker, and the amount of time involved. Generally, however, it is easier to measure using a beaker because the Erlenmeyer flask has angled sides while the beaker is cylindrical.
To determine which vessel (beaker or Erlenmeyer flask) is more accurate for measuring the evaporation of a liquid over time, it's important to consider the characteristics of each container.
Both beakers and Erlenmeyer flasks are commonly used in laboratory settings. However, there are some differences in their design that can impact accuracy when measuring evaporation.
Beakers are typically cylindrical with a flat bottom and straight sides, which makes it easier to measure the volume of liquid accurately. The straight sides provide a uniform measurement and allow for clear visibility of the liquid level. This makes it more accurate to track the evaporation process over a specific duration of time.
On the other hand, Erlenmeyer flasks have angled sides with a narrow neck at the top. The narrow neck can make it more challenging to accurately read the liquid level, especially as the amount of liquid decreases due to evaporation. The angled sides can also distort the measurement due to the changing surface area exposed to the atmosphere.
In summary, while both beakers and Erlenmeyer flasks can be used for measuring evaporation, beakers are generally considered more accurate due to their cylindrical shape and straight sides, which provide a better view of the liquid level during the evaporation process. It's important to consider the specific experiment's requirements, such as the size/volume of the vessel and the duration of the experiment, to determine the most appropriate container for measuring evaporation accurately.
