What are the markings on a graduated cylinder?
The graduated cylinder will usually have heavy markings at 10, 20, 30 . . . milliliters. There are usually smaller markings in between the larger units called graduations. Read the graduated cylinder to the nearest tenth of a milliliter (46.5 mL or 20.0 mL).
How many mL does each line on the graduated cylinder represent?
The scale divisions on a graduated cylinder are generally determined by its size. For example, the 50-mL graduated cylinder is divided into 1 mL increments. However, the scale of a 10-mL graduated cylinder is divided into 0.1 mL increments, and the scale of a 500-mL graduated cylinder is divided into 5 mL increments.
What does each line of a graduated cylinder represent?
A graduated cylinder, also known as a measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.
What are the numbered lines on a graduated cylinder?
On each of the 100mL and 250 mL graduated cylinders there are markings (graduations) that indicate the volumes along the length of the cylinder. Notice there are two sets of graduations on each cylinder, a graduation for larger volumes and smaller volumes.
How do you read a 100 ml graduated cylinder?
The 10-mL graduated cylinders are always read to 2 decimal places (e.g. 5.50 mL) and the 100-mL graduated cylinders are always read to 1 decimal place (e.g. 50.5 mL).
What do the lines in the graduated cylinder represent?
How much volume does each small tick mark represent?
There are 10 tick marks from 20 mL to 40 mL, so each tick mark represents 2 mL. Next, read the volume from the bottom of the meniscus.
What is the function of a graduated cylinder?
A graduated cylinder, measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured. Click to see full answer.
Why is the bottom of a graduated cylinder concave?
Another factor to consider is the meniscus which occurs due to the interaction between the liquid and the glass of the graduated cylinder. In the examples shown, the meniscus is concave and the bottom of the meniscus is the volume of the liquid.
What kind of cylinder is used to measure liquids?
Liquids are commonly measured using a graduated cylinder. A graduated cylinder is a cylinder with markings, usually in milliliters (mL). As with the ruler in the preceding discussion, different graduated cylinders have different markings. The student needs to know how the graduated cylinder is marked.
What kind of glass is a graduated cylinder made of?
Large graduated cylinders are usually made of polypropylenefor its excellent chemical resistance or polymethylpentenefor its transparency, making them lighter and less fragilethan glass.
