Absorb 5 mL of liquid in the pipet and then put it in your test tube, bottle, etc.
The main disadvantage of using a pipet in measuring the volume of a liquid is that you cannot dispense large quantities.
Yes, cause an aliquot is a small volume of something and I believe in this experiment you are also using a volumetric pipet, which should give you the exact volume of the aliquot.
A test may become unfair or the chemical you're using may cause a chemical reaction

Liquid Penetration test stands for a such test that can be done from the victim's end using petrol, kerosene, greaseetc.

Methods: using a pump, a liquid syphon, a funnel, pipettes, free flowing etc.

The meniscus. Make sure to always measure at that point. If your graduated cylinder/pipet/etc has the meniscus at 10 mL then the glassware has 10 mL in it.
An Epppendorf pipet is what is called a constant volume pipet. It consists of a barrel with a a push button on one end and a stem on the other. You attach a single use disposable tip to the stem. Some models allow you to set the volume to be dispensed, some are not adjustable. In use, , you depress the push button to the first stop, insert the tip into the liquid to be pipetted, and release the button smoothly to draw up the liquid. Then, transfer the pipet to the receiving vessel and depress the button past the first stop to the second stop, this dispenses the liquid and blows out the last drop to insure accuracy, then discard the tip before the next use. Every time you draw up liquid, you get the exact same volume, with very high precision.
Distillate is collected using a bent tip Pasteur pipet.

Fill a mug or a container with warm tap water. You are using warm tap water because, tap water contains microorganisms which will help flush out the chemicals and it is warm ,because warm water can cleanly stabilize your pipet so it is ready for it's next use. Pinch your pipet inside the water so it fills up to about 15-20 milliliters. Squirt in in the sink. Do the same thing for a few times. Atleast 5 times. Now your pipet is clean and ready for its next use.Why is it important to clean your pipet? It can contain chemicals from your previous experiment which will give inaccurate or wrong results and data.
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other. Hope this helped

The centrifugal pump is use to transfer a larger flow rate of liquid in a low pressure stage, while the booster pump is use to transmit less volume of liquid in a high pressure stage.
