    What is this? - ProProfs

    What is this?

    • Millimeter bottle

    • Erlenmeyer cylinder

    • Graduated cylinder

    Correct Answer
    A. Graduated cylinder
    Explanation
    A graduated cylinder is a laboratory instrument used to measure the volume of liquids accurately. It has a narrow cylindrical shape with measurement markings along its length. The other options, a millimeter bottle and an erlenmeyer cylinder, are not commonly used for measuring liquid volume. Therefore, the correct answer is a graduated cylinder.

    What are those things called that draw up liquid and squirt it out in drops?

    • Pipette

    • Turkey baster

    • Squirter

    Correct Answer
    A. Pipette
    Explanation
    A pipette is a tool used in laboratories to draw up liquid and dispense it in small, precise amounts. It consists of a long, narrow tube with a bulb at one end and a tapered tip at the other. By squeezing the bulb and then releasing it, the pipette can draw up liquid into the tube and then squirt it out in drops or small amounts. This makes it a suitable tool for accurately measuring and transferring liquids in scientific experiments. A turkey baster and a squirter, on the other hand, are not specifically designed for precise liquid dispensing like a pipette.

    What are two things that measure volume?

    • Balloons and tupperware

    • Beakers and graduated cylinders

    • Mass spectrometers and pipettes

    Correct Answer
    A. Beakers and graduated cylinders
    Explanation
    Beakers and graduated cylinders are both commonly used in laboratories to measure the volume of liquids. Beakers are cylindrical containers with a flat bottom and a pouring lip, while graduated cylinders are tall, narrow cylinders with measurement markings along the side. Both instruments are designed to accurately measure the volume of liquids, making them suitable choices for this purpose. Balloons and tupperware are not typically used to measure volume, and mass spectrometers and pipettes are used for different purposes in scientific experiments.

    To see things that are too small to be seen with the bare eye, one should use

    • A better set of eyes

    • A compound microscope

    • Safety goggles

    Correct Answer
    A. A compound microscope
    Explanation
    To see things that are too small to be seen with the bare eye, one should use a compound microscope. This type of microscope uses multiple lenses to magnify the object being observed. The combination of lenses allows for a higher level of magnification and resolution, enabling the user to see microscopic details that would otherwise be invisible to the naked eye. Safety goggles and a better set of eyes are not specifically designed for magnification and would not be effective in viewing small objects at a microscopic level.

    What is the unit for temperature?

    • Degrees Celsius

    • Degrees Fahrenheit

    • Hotness

    Correct Answer
    A. Degrees Celsius
    Explanation
    The unit for temperature is degrees Celsius. This is a widely used unit of measurement for temperature in the metric system. It is based on the Celsius scale, which sets the freezing point of water at 0 degrees Celsius and the boiling point at 100 degrees Celsius. Degrees Fahrenheit is another unit for temperature, but it is not the correct answer in this case. "Hotness" is not a unit of temperature measurement.

    What is the unit for volume?

    • Ounces

    • Milliliters

    • Milligrams

    Correct Answer
    A. Milliliters
    Explanation
    Milliliters is the correct answer because it is the unit commonly used to measure volume. Volume refers to the amount of space occupied by an object or substance, and milliliters is a metric unit of volume that is frequently used in scientific and everyday measurements. Ounces and milligrams are units of weight or mass, not volume, so they are not the correct units for measuring volume.

    What is the unit for length?

    • Farness

    • Inches

    • Centimeters

    Correct Answer
    A. Centimeters
    Explanation
    The unit for length is centimeters. Centimeters is a commonly used metric unit for measuring length. It is smaller than inches and is often used in scientific and mathematical calculations.

  • 9. 

    What do use a triple beam balance for?

    • Balancing three things

    • Weight

    • Mass

    Correct Answer
    A. Mass
    Explanation
    A triple beam balance is used 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. By placing the object on the pan and adjusting the weights, the mass of the object can be determined. This is different from weight, which is the force exerted on an object due to gravity. The correct answer, "Mass," accurately describes the purpose of a triple beam balance.

    What is this? - ProProfs

    What is this?

    • Milliliter bottle

    • Beaker

    • Erlenmeyer flask

    Correct Answer
    A. Erlenmeyer flask
    Explanation
    The correct answer is erlenmeyer flask. An erlenmeyer flask is a type of laboratory glassware that has a conical shape with a narrow neck. It is commonly used for mixing, heating, and storing liquids. The other options, a milliliter bottle and a beaker, are not specific types of glassware and do not have the same conical shape as an erlenmeyer flask. Therefore, the most appropriate option is the erlenmeyer flask.
