S. 4. 1.-Use basic scientific measurements and measurement tools

Volume

the amount of space something takes up

Mass

measurement of inertia, commonly considered the amount of material contained by an object and causing it to have weight in a gravitational field

Length

measurement of distance from end to end

Metric system(Systeme Internationale(SI))

Scientists use the this to measure and record data. This system uses base units and prefixes to increase or decrease size

SI base units

mass, length, and time are kilogram, meter, and second are all what

SI units

Systeme Internationale/ international system of units based on meters, kilograms, seconds, amperes, Kelvin, candela, and mole. Commonly known as the metric system- used to measure volume

Volume

This of a three-dimensional object has length, width, and height, all of which are measured in length units

Liter

Thus, the volume of a container 10 cm x 10 cm x 10 cm is 1,000 cm3. This SI base units for volume is more familiarly called this(measurement of liquid volume)

Dimensional analysis

This is used to convert measurements from one unit size to another

Conversion factor

This expresses the relationship between units that is used to change the quantity without altering the value of the measurement

Length

typically measured with a ruler or meter stick/ is the distance from end to end of an object and is used to describe width, height, and length

Liquids

Several types of glassware can be used to measure the volume of what

Volume

This of solids can be calculated by multiplying the measurement of length, width, and height. The sides can be measured used rulers or metersticks

Volumetric pipette

The most accurate tool in measurement large volumes is a volumetric flask and small volumes are best measured using a this(device used for precise measurement of small amounts liquid volume)

Graduated cylinders

narrow cylinder used to measurement liquid volume/ can also be used to measure a range of volumes in the laboratory, but they are less accurate than volumetric flasks or pipettes

Meniscus

Remember that liquids form a this in a measurement tool. It is the curve formed at the top of a liquid in response to its container. Its curve can be upward(concave), downward(convex), or flat, depending on the properties of the liquid and the container. When measuring the volume of a liquid, make sure that the line you are reading is even with the center of the this

Balances

used to measure the mass of an object

Mass

the amount of matter in an object

Triple-beam balance and electronic balance

There are two types of balances used to measure mass:

Electronic balance

This balance is more common because it is easier to use

kilograms (kg)

Large items with a large mass would likely be measured using this

Millimeters

For length, small things like insects and fingernails should be measured in millimeters

Centimeters; meters

Objects like the width of a piece of paper can be measured in this, whereas the height of a door or a ceiling should be measured in this

Kilometers(km)

The distance between two towns can be measured in what
