4. Activity 2 1. Name at least 2 laboratory apparatus you found inside the lab.2. Can you identify their uses? 3. Why is it important to use laboratory apparatus?
1. Beaker and Watch glasses
2. A beaker is a common container in most labs. It is used for mixing, stirring, and heating chemicals. A watch glass is just a round piece of glass that is slightly concave/convex (think of a lens). It can hold a small amount of liquid or solid. They can be used for evaporation purposes and also can function as a lid for a beaker.

6. 5 laboratory apparatus used for investigation describe their function
1. Microscope:
A microscope is a very basic and needful equipment of biology laboratory. A simple light microscope (compound microscope) is the one, and it uses natural light and a series of magnifying lenses to observe a tiny specimen.
2. Test tubes:
The next very common apparatus are the test tubes. They are usually cylindrical pipes made up of glass, with a circular opening on one side and a rounded bottom on the other side. They come in different sizes but the most common standard size is 18*150 mm. Test tubes are one of the most important apparatus as they are functional from storing to mixing reagents in any chemical or biological reactions.
3. Beakers:
Beakers are another cylindrical utensil made up of glass, with a flat bottom and the upper opening having a spout. They are of varying sizes and are used to hold, heat, or mix substances with the proper measure.
4. Magnifying glass:
As the name suggests, it is used to view enlarged or magnified images of objects or read the small calibrations marked on many equipments. It has a convex lens for object enlargement and usually has a wooden handle to hold it.
5. Volumetric flask:
This is one of the most important equipment of any lab, which is made up of glass and is calibrated to hold a precise volume of liquids at any precise temperature. Different sizes of volumetric flasks are available, each calibrated for exact measurement of liquids and solutions. In chemistry labs, it is mostly used in the preparation of standard solutions.

17. give me at least 5 laboratory apparatus and their uses.
1. Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations.
2. Bunsen burners are sources of heat.
3. Burets are for addition of a precise volume of liquid. The volume of liquid added can be determined to the nearest 0.01 mL with practice.

20. What Apparatus is used in separating immiscible liquids?a. filter funnelb.microscopec.seperating funneld.thermometer
Answer:
i think c
Explanation:
c is the answer
Answer:
C
Explanation:
Decantation can be used to SEPARATE IMMISCIBLE liquids that have different densities. For example, when a mixture of water and oil is present in a beaker, a distinct layer between the two consistency is formed, with the oil layer floating on top of the water layer.

27. Why is it essential that you know the laboratory apparatus and it’s use?
Answer:
We should always know your lab equipment well before you do any type of experiment because without the proper knowledge of your equipment you will not know how to use your materials or how to correct a mistake that you could make with your equipment. Over and above the reasons mentioned, knowing one's science equipment will only aid in having a successful experiment and might help in correcting errors.
