What is the formula for density?
D=M/V
What is the definition of mass?
What is the measure of how much matter is in an object.
What is the definition of volume?
What is the amount of space an object occupies.
A graduated cylinder has 50ml of water. You place a cube into the cylinder and the water level rises to 68ml. What is the volume of the cube?
What is 18 mL
What is the tool used to measure volume of an irregular object (like a rock)?
A graduated cylinder
What is the density of pure water?
What is 1.0 g/ml
True or false. You will have the same mass on Jupiter as you do on Earth.
True. Your mass stays the same even if the amount of gravity changes.
If I have a cube that is 3cm on all sides, what is its volume?
V=LxWxH
V= 3cmx3cmx3cm
V=3x3=9 9x3=27
V=27 cm3
what is the volume of this cube?
v= lxwxh
v=10mx4mx5m
v=40 x 5
v=200m3
What are the tools used to measure length?
What is a meter stick or metric ruler.
What is the density of an object with a mass of 48 g and a volume of 8 cm3?
6 g/cm3
True or False: You use a graduated cylinder to measure mass?
What is False.
What is tool to measure the volume of a regular solid object (like a box)?
a ruler
What is the volume of this liquid?
15ml?
What tool is used to measure liquid volume?
What is a graduated cylinder?
What will happen if you place an object with a density of 8 g/cm3 into a liquid that has a density of 1.33g/cm3?
It will sink.
What tool do you use to measure mass?
A triple beam balance
What is the curved surface you seen when you measure the volume of a liquid in a graduated cylinder?
What is the meniscus.
What is the volume of a cube with a length of 27 cm, a width of 3 cm, and a height of 8 cm?
What is 648 cm3.
What is the tool sometimes needed for finding density?
calculator
Describe one useful way in which density data can be used.
Density data can be used to:
-identify unknown materials (cube lab)
-determine whether an object will sink or float
What has more mass, a kilogram of feathers or a kilogram of brick?
Trick question, their masses are the same, their densities are different.
What is a way to find the volume of an irregular object?
Displacement
or
placing the object in water and calculating the change in the water from before to after.
what is volume of this object.
180ml-150ml=30ml
what units can density be in
g/cm3
g/ml
