To find density of matter, you must______________
divide mass by volume.
Mass is how much _______________ an object has.
Volume is ___________________
how much space an object occupies.
A tool to measure mass is _________________
a triple beam balance.
A cylinder is placed on the left side of a double pan balance. A block is added to the right side of the balance and the beam is balanced (level). Which of the following statements is true?
c. the objects have equal masses
B. Density of B is greater than that of A.
What can you conclude about materials 1 and 2?
C. material 1 has more mass than that of 2.
A group of students were trying to find the relative density of four objects. The table below represents the experimental data. Use the data table to answer the following question.
Suppose we have a stone with a mass of 15 g, and volume of 5 cm3. What is the mass of 1 cm3 of this stone?
If you have two different objects with the same mass and you place them into water, you notice that one object floats and the other sinks. How can this be possible?
If you increase the volume (the area it takes up) you decrease the density. If you decrease the density smaller than water's density, it will float. If you decrease the volume (the area it takes up) it will increase the density. The big object will float and the small object will sink.
If you hold volume constant, how does mass affect the density?
If you have a bigger mass you have a more dense object. If you have a smaller mass you have a less dense object.
The SI unit for mass is the ______________.
1 Kilogram= 1000 grams
What is the best way to report the data given
Find the average of the four measurements
How many bins would you need for the following data sets if the bins in your histogram had to be in increments of 10?
you would need four bins
What object or liquid is most dense?
What happens to the system's mass when you dissolve a solid into a liquid?
It stays the same
What happens to the mass of a system when you mix two liquids together and form and new solid substance?
It stays the same
On a density graph which is the independent variable; mass or volume?
Volume is on the x axis
On a desnity graph, which variable is the dependent variable; mass or volume?
Mass is on the y axis
What is the density of substance 1?
Change in mass divided by the change in volume would equal approximately 16-17 g/cm3
How do you find density from a graph?
the change in the mass divided by the change in the volume
How do you find volume from the original density equation?
mass divided by density
How do you find the mass from the original density equation?
density times volume
How do you find mass from a density graph that also reports a starting mass?
density times volume plus starting mass
If you have two substances and they contain the different densities and the same amount of mass, they could be the same substance by.....
changing the temperature or adding more volume
