Graduated Cylinder Reading Practice Quiz

Position B is the correct position to read a graduated cylinder because it allows for accurate measurement of the liquid level. In this position, the observer's eye should be at the same level as the meniscus (the curved surface of the liquid) to avoid parallax error. This ensures that the measurement is not affected by the angle of view, providing a more precise reading.

When taking measurements from a graduated cylinder, it is essential to read the scale at eye level with the meniscus, the curved surface of the liquid. This position helps to avoid parallax error, which occurs when the measurement is viewed from an angle rather than straight on. Viewing the meniscus at eye level ensures that you accurately see the lowest point of the liquid's curve, leading to a correct volume reading.

In a graduated cylinder, the volume of liquid is measured at the bottom of the meniscus, which is the curve formed by the surface tension of the liquid. If the meniscus rests at the 25 mL mark, then the volume of the liquid is precisely 25 mL. It is crucial to note that the reading should be taken from the bottom of the meniscus, as this point indicates the true volume of the liquid.

The volume of liquid in the graduated cylinder is measured by observing the meniscus, the curved surface of the liquid. The meniscus should be read at eye level, and the volume is determined by noting the mark that aligns with the lowest point of the meniscus. In the given image, the meniscus aligns with the 6.6 mL mark on the graduated cylinder, indicating that the volume of liquid present is 6.6 mL.

The volume of liquid in the graduated cylinder is measured by observing the meniscus, the curved surface of the liquid. The meniscus should be read at eye level, and the volume is determined by noting the mark that aligns with the lowest point of the meniscus. In the given image, the meniscus aligns with the 24 mL mark on the graduated cylinder, indicating that the volume of liquid present is 24 mL.

The volume of liquid in the graduated cylinder is measured by observing the meniscus, the curved surface of the liquid. The meniscus should be read at eye level, and the volume is determined by noting the mark that aligns with the lowest point of the meniscus. In the given image, the meniscus aligns with the 9 mL mark on the graduated cylinder, indicating that the volume of liquid present is 9 mL.

The volume of liquid in the graduated cylinder is measured by observing the meniscus, the curved surface of the liquid. The meniscus should be read at eye level, and the volume is determined by noting the mark that aligns with the lowest point of the meniscus. In the given image, the meniscus aligns with the 38 mL mark on the graduated cylinder, indicating that the volume of liquid present is 38 mL.

Look at the marked values: You have 20, 40, 60, and 80.

Calculate the difference: The difference between each marked value is 20 (e.g., 40 - 20 = 20).

Consistent intervals: The lines appear to be evenly spaced.

Therefore, each line on the beaker represents an increase of 20 units.

When the liquid level falls between two graduation marks, interpolation is necessary to estimate the volume accurately. This involves estimating the volume by considering the distance between the two marks and where the meniscus lies between them. For example, if the liquid is halfway between 20 mL and 25 mL, you might estimate the volume to be approximately 22.5 mL. This method provides a more precise measurement than simply rounding to the nearest whole number, ensuring better accuracy in scientific measurements.

The volume of liquid in the graduated cylinder is measured by observing the meniscus, the curved surface of the liquid. The meniscus should be read at eye level, and the volume is determined by noting the mark that aligns with the lowest point of the meniscus. In the given image, the meniscus aligns with the 2.65 mL mark on the graduated cylinder, indicating that the volume of liquid present is 2.65 mL.
