Identify commonly used lab equipment. (beaker, graduated cylinder, triple beam balance, test tube, Patri dish)
I really don't need answer. Does this means I have to write definitions for each lab equipment???? I really need help.
Yes. You should also know what they look like.
That's a PETRI dish, not a Patri dish.
I KNOW i click on the a by mistake
thx
You're welcome.
I can definitely help you with that! Instead of writing definitions for each lab equipment, I can explain how to identify commonly used lab equipment. This way, you will understand what they are and how they are used. Here's a breakdown of the equipment you mentioned:
1. Beaker: A cylindrical container with a flat bottom and a lip used for holding, mixing, and heating liquids. It is usually made of glass or plastic and comes in various sizes.
2. Graduated cylinder: A tall, narrow cylindrical container used for measuring the volume of liquids. It has precise measurement markings along the side to accurately determine the volume.
3. Triple beam balance: A device used to measure the mass of an object. It consists of a beam with three weights that can be moved along graduated scales to find the mass.
4. Test tube: A small cylindrical container with a rounded bottom used for holding and mixing small amounts of liquids or solids during experimental procedures.
5. Petri dish: A shallow, cylindrical dish with a lid commonly used in microbiology to culture bacteria or other microorganisms. It provides a sterile environment for growth.
To identify lab equipment, think about their purpose and distinctive features. For example, beakers usually have a spout for pouring, graduated cylinders have measurement markings, triple beam balances have adjustable weights, test tubes are small and have no lid, and Petri dishes are shallow and have a lid for protection.
By understanding these characteristics and thinking about the function of each piece of equipment, you will be able to identify commonly used lab equipment easily.
