What are the SI units for density?
g/units3
This state of matter has a definite shape and volume.
Solid
Matter is
Anything that has mass and takes up space.
What tool is used to find mass?
Scale/ triple beam balance
What tool do you use to find the volume of an irregular shaped object?
Graduated cylinder
What is the formula for density?
Density= mass/volume
A state of matter with no definite shape but it does has a definite volume
Liquid
The most basic building blocks of matter is...
atoms/elements
Why do we talk about mass instead of weight?
Mass does not change, weight changes based on gravity
When you add water to a beaker that changes its......
volume
If an objet has a density of .67, will it sink or float in water?
Float
This state of matter does not have definite shape or definite volume
Gas
If two objects have the same density and the same mass what is the only thing that can be different?
The Volume
A triple beam balance reads
30 g
200 g
2.5 g
What is the mass of the object?
232.5 g
If you have a rectangular prism with a length of 8m, a width of 2m , and a height of 4 m, what is the volume? (Use proper units)
64 m3
If you know the volume of an object is 200 cm3 and the mass is 2000 g, then the density will be....
10 g/cm3
What do you need to add or take away to change the state of matter?
Energy/ heat
What is one thing that is not matter
Light, energy, heat
A triple beam balance shows 234 grams but the line is above the middle, what can we tell about the object?
The object is heavier then 234 grams
If you put a star into a graduated cylinder that read 40 g before and now it reads 52 g, what is the volume of the star (Proper units included)?
12 cm3
If you know that the density of an object is .1 g/cm3 and the volume is 3000 cm3, what is the mass of the object?
300 grams
No matter how many times you change a state of matter, this is never lost.
Amount of matter
What is the one thing that has to change from one element to a next?
The number of protons
