What 3 ways can we measure volume?
To illustrate the effects of precision on data, volumes will be determined by three different methods: geometrically (measuring lengths); water displacement; and pycnometry. The composition of a mixed brass-aluminum cylinder and the volume of empty space within a hollow cylinder will also be found.

How do we measure liquid?
To measure liquid with a measuring cup, bend down so you are at eye level with the cup. Pour your liquid into the measuring cup, watching the level of the liquid the whole time. You can also purchase an angled measuring cup, which allows you to accurately measure liquids without having to bend down.
The Volume of a Liquid
The volume is one of many ways to scientifically describe an object or substance. It measures the occupancy of the object in a three-dimensional space; therefore, it takes into consideration the object's length, width, and height.
Measuring Liquid Volume
The shape of liquids change according to their recipients. If one pours one liter of water in a jar or in a bowl, the shape of that amount of water will vary. Its volume, however, will remain the same: one liter. The most basic method of liquid volume measuring is to pour the substance into a graduated recipient.
How to Find the Volume of a Liquid Using Liquid Measurement Tools
Pouring a liquid into a graduated recipient is the simplest form of measuring the volume of a liquid. In science laboratories it is common to see a variety of these recipients that can be used for different tasks. In all cases, the volume marks imprinted on the vessels are the reference for measurement.
How accurate are graduated cylinders?
The markings or calibrations on a graduated cylinder are more precise and accurate, but should not be used if the cylinder is less than 50 percent full . The important thing to remember about beakers, flasks and cylinders is that the volume of the liquid may be measured, but if it is poured out, a certain amount will remain in the vessel. ...
What instrument is used to measure volume?
The volume of a liquid can be measured in the lab with a beaker, graduated cylinder, burets, pipette or micropipette. The instrument used depends on the actual volume of the liquid and the desired degree of accuracy.
Why do we use burets in titration?
Burets are useful when you are doing a titration, which is a process used to determine the precise concentration of a liquid needed to bring a reaction to completion. Let's walk through a very simple example of a titration to better understand the use of a buret.
What is the valve on a buret called?
The valve at the bottom of the buret, which is called the stopcock, allows you to flow or drip precise amounts of liquid into a receiving container. Burets are read from top to bottom, so in a 50 mL buret, which is the most common size, the top number is 0 mL, and the bottom number is 50 mL. When you use a buret to measure volume, you are actually ...
What is the best way to measure liquid volume?
Burets. You just learned a good way to measure liquid volume, but some experiments require you to be even more precise. In these cases, you might want to use burets. Burets are cylindrical containers with graduations marked on the side and a valve at the bottom.
What is the purpose of a buret?
When you use a buret to measure volume, you are actually measuring the amount of liquid you dispensed. This is a bit more involved than a graduated cylinder and requires a simple math equation. For example, to determine the volume of liquid you used in an experiment, you would subtract the initial volume from the final volume.
What is a graduated cylinder made of?
Graduated cylinders are typically made of glass or plastic, which is actually significant. It's important because we know that water and other liquids tend to cling to these materials. This attraction of liquid to the container causes the water level to be slightly higher at the edges and lower in the middle.
Why do scientists need to measure liquid volume?
For some experiments, being off by a few milliliters could alter the result. Because measurements need to be exact , a scientist needs the right tool for measuring liquid volume. The tool the scientist selects will depend on how much liquid he must measure ...
How many mL increments are there in a graduated scale?
If the cylinder is big, and can hold 500 mL of liquid, then the markings on the graduated scale would be divided into 5 mL increments. Five mL is about a teaspoon of liquid. If the cylinder is small and holds only 10 mL of liquid, then the markings would be in 0.1 mL increments, which is a tiny droplet.
Why is it important to read the meniscus at eye level?
It is important to properly read the meniscus at eye level and be precise when measuring in order to accurately find a volume.
Which is better: a graduated cylinder or a beaker?
Graduated cylinders are more precise and ideal for a small amount of liquid because its hash marks measure up to 250mL, while beakers or Erlenmeyer flasks are better for larger measurements because they can contain up to 1000 mL.
What is volume measurement?
At its most basic level, volume is simply a measure of space. When measuring the volume of a liquid, sometimes referred to as capacity, the units liters (L) and milliliters (mL) are used.
What is volumetric labware?
For graduated cylinders, the margin of error, or tolerance, is about 1%. Volumetric labware is for measuring liquids with precision. Volumetric flasks, burettes, and pipettes made ...
What is a burette?
Burettes. Burettes are long, narrow glass tubes with hash marks for measurement along the side. They have one tapered end to deliver precise liquid measurements and a stopcock (rubber stopper) used to control the flow of liquid in titrations.
What is the purpose of a serological pipette?
Serological pipettes are used to transfer liquid amounts from less than 1 mL to up to 50 mL. They may be plastic, disposable pipettes, or reusable glass.
Why do we use burettes in titration?
The stopcock can be turned to allow small amounts of liquid to flow out of the tube. Burettes are commonly used to measure precise, variable volumes of solution, primarily for titration, and mixing a known measurement of one reactant until the precise reaction is achieved.
What is lab glassware?
Lab glassware, made from borosilicate glass, is strong and hard to break. It is suitable for containing chemical reactions and heating liquids to high temperatures. The accuracy of the markings on laboratory glassware varies. Larger containers, like beakers and flasks, are typically ±5% of the total volume. They are generally used only ...
What is an Erlenmeyer flask?
Erlenmeyer Flasks. These flasks have a narrow, cylindrical neck and a conical base with a flat bottom. They are named after Emil Erlenmeyer, the German organic chemist who designed the glassware in 1861. Erlenmeyer flasks are often used for mixing and heating solutions.
What is a hash mark?
A hash mark is printed on the side for precise measurement at a specific temperature. They’re calibrated to contain a precise volume at a certain temperature. Volumetric flasks are typically used for precise dilutions to prepare known solutions.
What is a measuring cup?
Measuring Cups • Measuring cups and measuring spoons are used to measure liquids (water, oils, etc) and solids (sugar, salt, etc). • They come in different sizes- you’ve probably seen them if you’ve ever made brownies or a cake- the ½ cup, the ¼ cup, and so on. 8.
How to measure volume?
Measuring Volume Steps to measure volume: – Make sure your eyes are level with the container you are measuring – Read the measurement on the scale. – Record your data – You measure solids the same way you do liquids. Make sure the top is smooth before you read the volume. 80 mL. 11.
