Explain why it's important to know the temperature when testing if your micropippetor is correctly calibrated

Explanation:

It is important to know the temperature when testing because the volume of a liquid substance changes with the variation of the temperature, and the micropipette just measure the volume of the liquids. Therefore, if you want to be precise in your measurements you need to consider the temperature factor and calculate the new volume.

do u have any choices to choose from ? ?

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
