JudyA balance is used to measure the mass of an object by comparing it to known weights, while a graduated cylinder is used to measure the volume of a liquid. The balance provides a quantitative measure of mass in grams, while the graduated cylinder provides a quantitative measure of volume in milliliters.

What is the difference between a balance and graduated cylinder?
A balance is used to measure the mass of an object, while a graduated cylinder is used to measure the volume of a liquid. Balances typically use a scale to determine weight, while graduated cylinders have volume markings along the side for measurement.
What is the difference between a test tube and a graduated cylinder?
A test tube is a cylindrical container used for holding small amounts of liquid or solids for testing or mixing. A graduated cylinder is a tall, narrow cylinder with volume markings used to measure the volume of liquids. The main difference is that a graduated cylinder is used for precise volume measurements, while a test tube is for general purposes.
What is the difference between pipette and graduated cylinder?
A pipette is a more precise measuring tool used for transferring small volumes of liquid accurately, while a graduated cylinder is used to measure larger volumes. Pipettes typically have a finer scale for precise measurements, while graduated cylinders are suitable for general volume measurements.
Why does a concave meniscus form when water is in a graduated cylinder?
A concave meniscus forms in a graduated cylinder with water due to adhesive forces between the water molecules and the walls of the cylinder. This causes the water to cling to the walls, resulting in a concave shape.
What is the fill line of a graduated cylinder called?
The fill line of a graduated cylinder is known as the meniscus. It is the curved surface of a liquid in the cylinder caused by the surface tension between the liquid and the glass. Scientists must take measurements at the bottom of the meniscus for accuracy.
