Question

A measuring jar is graduated in ml from bottom to top.
A. True
B. False

Answer 1

Hint: You can start by briefly describing the measuring jar. Then explain how measuring jars are measured, including points like the units. Also, remember to explain the direction of labelling on the measuring jar.

Complete answer:
A measuring jar is a type of measuring utensil that is used in labs and kitchens. They are used to measure liquids like honey, or chemicals. Measuring jars can be made up of plastic, glass, or metal and they are usually transparent or translucent so we can see the amount of liquid in the measuring jar.

The measuring jar is labeled with measurements that are usually in milliliters. The labels are printed on the measuring jar with the help of very precise equipment that is programmed for this job.
A measuring jar is shown in the figure below

As you can see the measuring jar is labeled from the bottom to the top. As to why the label is labeled from the bottom to the top, the reason is quite simple. When you pour a liquid in the measuring jar the jar starts to fill at the bottom. While pouring the liquid fills from the bottom to the top, so the labels also start from the bottom (smallest at the bottom of the measuring jar and largest at the top.

So, the correct answer is “Option A”.

Note:
The measuring jars or in general, any lab equipment like test tubes, flask, cylindrical flask, etc. are all made up of polypropylene. If we were to use plastic or metal to make lab equipment then there is a possibility that they may react with the liquids we are trying to measure and it may affect the experiment.
