Mass, Volume & Density Flashcards
What’s matter?
Matter is anything that occupies volume and has mass.
What’s mass?
Mass is characteristic of how much matter they contain.
The basic unit is the (kg)
What’s volume?
Volume is the space an object occupies.
Basic Unit: cubic meter (m3)
Everyday Life: litre (dm3)
How do we measure mass?
Using scales.
How do we measure volume with liquids?
With specific instruments like the Pipette, Burette, Graduated cylinder and Volumetric flask.
Which instruments are used for measuring volume and which are used to transfer liquids?
Pippete: Transfer Specific volume of Liquids
Burette: Transfer Variable volume of Liquids
Graduated cylinder: Measure volume
Volumetric flask: Measure fixed volumes of liquid.
Different ways of calculating volume.
1: With instruments and containers.
2: If regular shape with formulas.
How do we measure volume with solids?
With water, container & the difference before and after is the volume.
What’s density?
Density is a defining characteristic that describes the concentration of mass in a specific volume.
How do we calculate density?
Density = Mass / Volume
How do we calculate mass and volume with formula?
Mass = Density * Volume Volume = Mass / Density
What are the units of density?
g/cm3
kg/m3
What are extensive properties and examples?
Extensive properties are properties in which you cannot distinguish one material from another & depend on the amount of substance analyzed.
Example: Mass & Volume
What are intensive properties and examples?
Intensive properties don’t depend on the amount of matter analyzed.
Example: Density
What is a specific property & example?
A specific property is a property which distinguished a substance from another.
Example: Density
