Mass Volume Density Flashcards
4 tools to measure mass of an object
Double pan
Quad balance
Triple beam balance
Scale
What is mass
Amount of matter in an object
How does mass differ from weight
Weight is how much gravity is pulling and mass is how much matter there is in something
How do you measure mass on a triple beam balance?
Start all riders at zero, move the 100gram rider first but don’t go over the pointer, then move the 10 gram rider but don’t go over the pointer, with the top of our pen or pencil move the 1 gram order until the two pointers line up.
Why is it important to make the scale zero before taking measurements?
So you can get the correct measurement
How do you find the mass of water
You put the empty beaker on scale,
find the mass of the beaker,
Fill beaker with water,
Subtract the two masses the answer is the mass of water alone
What tools do we use to measure weight
Electronic and spring scales
Define volume
The amount of space an object takes up
What is a regular object
Something that has a solid a
Shape
What tool is used to measure the volume of a regular object
Ruler
What is the equation to find the volume of regular object
Length time width times height
What are the names for two tools you use to measure volume of a liquid
Graduated cylinder and Beaker
Where do measure volume of a Liquid from
Meniscus
Liquid volume is mainly measured in…
Liters or milliliters
What is an irregular object
Something that Has an irregular shape that can’t be measured using a ruler
What is the name for the process of measuring volume of an irregular object
Displacement method
What tool would you use to measure volume of a shell
Graduated cylinder or beaker
How do you measure the volume of an irregular shaped object
Fill graduated cylinder with water Read meniscus Put object in Read meniscus again Subtract to measurements
How do you find density of an object
Find mass w/ balance
Find volume w/ ruler
Divide m\ v
What is the equation for finding density
Mass/volume
Mass divided by volume
Density is measure in…
g/cm3
What is the density of water
1.0g/ml
What do you call an object that does not float or sink
Suspended
Given the density of an object how do you determine if it will float or sink in water
If it has a density less than one it will float
