Beakers
- D.
Rubber stoppers
Correct Answer
C. BeakersExplanation
Beakers are cylindrical containers with a flat bottom and a lip for easy pouring. They are commonly used in laboratories for holding, mixing, and heating liquids. Beakers are preferred over test tubes and graduated cylinders for tasks that require larger volumes of liquid or for reactions that produce gases. Rubber stoppers are used to seal containers and prevent leakage. Therefore, beakers are the most suitable option for the given question.Rate this question:

What is this?
- A.
Test tube rack
- B.
Triple beam balance
- C.
Electronic balance
- D.
Test tube holder
Correct Answer
C. Electronic balanceExplanation
The correct answer is "electronic balance" because it is the only option that is a measuring instrument used to determine the mass of an object. A test tube rack is used to hold test tubes, a triple beam balance is another type of weighing instrument, and a test tube holder is used to hold test tubes during experiments. Therefore, the electronic balance is the most appropriate answer as it is specifically designed for measuring mass.Rate this question:

Florence flasks
- B.
Beakers
- C.
Erlenmeyer flasks
- D.
Graduated cylinders
Correct Answer
A. Florence flasksExplanation
Florence flasks are a type of laboratory glassware commonly used for heating liquids. They have a round bottom and a long neck, allowing for easy swirling of the contents without spilling. Florence flasks are designed to evenly distribute heat and are often used in distillation and reflux processes. They are not as commonly used for measuring or precise volume measurements like graduated cylinders. Beakers are similar to Florence flasks but have a straighter shape and are used for a variety of purposes in the lab. Erlenmeyer flasks have a conical shape and are commonly used for mixing and titration. Therefore, the correct answer is Florence flasks.Rate this question:

Correct Answer
A. FunnelExplanation
A funnel is a cone-shaped utensil with a narrow tube at the bottom, used to pour liquids or other substances into containers with small openings. It is commonly used in cooking, laboratory experiments, and various other tasks that require transferring liquids or powders. The other options, such as beaker, thermometer, and dropper, do not have the same shape or purpose as a funnel, making funnel the correct answer.Rate this question:

Correct Answer
B. GogglesExplanation
The given options are test tube, goggles, electronic balance, and Erlenmeyer flask. Out of these options, goggles are the only item that is used to protect the eyes. Test tubes are used to hold small amounts of liquid, electronic balances are used to measure the mass of an object, and Erlenmeyer flasks are used for mixing and heating liquids. Therefore, the correct answer is goggles.Rate this question:

- D.
Graduated cylinder
Correct Answer
D. Graduated cylinderExplanation
A graduated cylinder is a cylindrical container used to measure the volume of liquids accurately. It has markings on its side, allowing precise measurements to be taken. This is different from a beaker, which is used for general mixing and holding of liquids, a funnel which is used for transferring liquids between containers, and a test tube which is used for holding small amounts of substances for reactions or observations. Therefore, the correct answer is graduated cylinder.Rate this question:

Dropper
- D.
Test tube holder
Correct Answer
B. ThermometerExplanation
The given options are test tube brush, thermometer, dropper, and test tube holder. Out of these options, the correct answer is thermometer. A thermometer is an instrument used to measure temperature. It typically consists of a glass tube filled with a liquid, such as mercury, that expands or contracts with temperature changes. By observing the level of the liquid, the temperature can be determined. The other options, such as test tube brush, dropper, and test tube holder, are not used for temperature measurement but for other laboratory purposes.Rate this question:

Graduated cylinder
Correct Answer
C. Triple beam balanceExplanation
A triple beam balance is a type of weighing scale used in laboratories to measure the mass of an object. It consists of a beam with three sliding weights that can be adjusted to find the balance point and determine the mass. This is different from an electronic balance, which uses electronic sensors to measure mass, a test tube rack, which is used to hold test tubes, and a graduated cylinder, which is used to measure liquid volume. Therefore, the correct answer is triple beam balance.Rate this question:

Droppers
Correct Answer
C. Rubber stoppersExplanation
Rubber stoppers are commonly used in laboratories to seal test tubes and other glassware. They provide a tight and secure seal, preventing any leakage or contamination of the substances inside the test tubes. Rubber stoppers are flexible and can easily be inserted or removed from the test tubes. They are also durable and can withstand high temperatures and chemicals, making them suitable for a variety of experiments and reactions. Therefore, rubber stoppers are an essential tool in any laboratory setting.Rate this question:

What is this?
- A.
Coverslips
- B.
Slides
- C.
Microscope
- D.
Beaker
Correct Answer
B. SlidesExplanation
Slides are thin, flat, rectangular pieces of glass or plastic that are used to hold specimens for observation under a microscope. They provide a smooth and transparent surface for the specimen to be placed on, allowing light to pass through and enabling clear visualization. In contrast, coverslips are smaller pieces of glass or plastic that are used to cover the specimen on the slide, protecting it and preventing contamination. While a microscope is the instrument used for magnifying and examining specimens, a beaker is a cylindrical glass or plastic container used for holding and mixing liquids and chemicals in a laboratory setting.Rate this question:
