ProfessorA 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 name of the test tube that measures?
A graduated cylinder is a type of test tube that measures volume with markings along its side.
Which property of water causes water to curve in a graduated cylinder?
The property of water that causes it to curve in a graduated cylinder is called surface tension. Surface tension is due to the cohesive forces between water molecules, causing them to attract and pull each other, leading to a curved surface at the edges of the water in the cylinder.
What is the capacity of the graduated cylinder in milliliters?
The capacity of a graduated cylinder can vary depending on its size. Common sizes include 10 mL, 25 mL, 50 mL, 100 mL, and 250 mL. It is important to check the markings on the cylinder to determine its specific capacity.
A researcher needs to pour exactly 4 mL of hydrochloric acid into six different test tubes Which What instruments would best help the researcher correctly distribute the solution?
A micropipette would be the best instrument for accurately dispensing 4 mL of hydrochloric acid into each test tube. Alternatively, a graduated cylinder with a precise scale could also be used.
How a water-filled graduated cylinder is inverted in a pan of water?
When a water-filled graduated cylinder is inverted in a pan of water, the water in the cylinder will remain in place due to the force of gravity holding it in. The air pressure pushing against the water at the top of the cylinder also helps to keep the water in place.
