What is the formula to solve for density?
Density= mass/volume
100
What is the amount of space and object occupies?
Volume
100
Which statement is true of all matter? A. It has mass B. It can be seen C. It exists only as a solid D. It maintains its size and shape.
A. It has mass.
100
If the size of a same changes, which physical property will also change? A. density B. mass C. reactivity D. volume
D. volume If the size of the sample changes, the amount of space it occupies also changes. However, if the object is still the same material and in the same state of matter, all other properties will remain unchanged.

How can you tell that a chemical reaction has occurred when you mix vinegar and baking soda?
The presence of bubbles, which indicate the presence of a gas, which was not in either material before they were combined.
200
Find the density of an object that has a mass of 40 g and a volume of 8 mL.
density = 5 g/mL3
200
What is a property that remains unchanged, even after physical and chemical changes take place?
Mass
200
If the volume of an object doubles, what happens to the density of the object? (remember, mass remains unchanged).
The density of the object will decrease by half.
200
Which specific property causes rust to form on iron when it is exposed to water over a period of time?
Reactivity.
200
You find 3 liquids in your kitchen and pour them all into one container. You notice that 3 liquids do not mix and you can clearly see that one liquid is at the bottom of the container. Which property explains why the liquids maintained separate, into layers, of the container?
The liquids have different densities. The liquid at the bottom of the container is the most dense, while the liquid at the top of the container is the least dense.
300
find the mass of an object with a density of 5g/cm3 and a volume of 9 cm.
mass = 45 g
300
Name a specific property that creates a new substance.
Flammability and reactivity
300
If an object has a mass of 30 g on Earth, will the mass be more than, less than, or equal to 30 g on the moon?
The mass will be equal to 30 g.
300
A statue and a coin are made of the same materials. Which property will most likely be the same for both objects? A. mass B. reactivity C. volume D. shape
B. reactivity
300
Which is an example of q physical change? A. Water turns to steam when boiled. B. Carbon combines with oxygen to form carbon dioxide gas. C. Rust forms on iron when exposed to water. D. Ashes form when wood is burned.
A. Water turns to steam when boiled. Water vapor is still water! It is just in the form of a gas, the chemical properties do not change.
400
Find the volume of an object with a mass of 20 g and a density of 4 g/mL3
5mL
400
What is the name of property that describes when a material dissolves into a liquid?
Solubility
400
If an object weighs 50 pounds on the moon, will it weigh more, less, or equal to 50 pounds on Earth.
The object will weigh more than 50 pounds on Earth. In fact, the object will weigh 6 times more on Earth, or 300 pounds.

Joe drops a jar of quarters while visiting the beach. He wants to quickly separate the quarters from the sand. What tool could he use to quickly separate the quarters from the sand?
A magnet
400
Ellie find a sea shell while at the beach. She wants to calculate the volume of the shell. What can she do to find the volume?
Use water displacement. She can put the shell completely in a pre-measured amount of water, then measure the volume of the water with the shell. She will then subtract the volume of the water without the shell from the volume of the water with the shell. The difference is the volume by water displacement.
500
Find the volume of an object with a density of 9 g/cm3 and a mass of 90 g
10 cm3
500
What is the amount of mass per unit of volume called?
Density
500
If an ice cube is placed on a hot beaker and becomes a liquid, then a gas, which property remains unchanged? A. temperature B. volume C. mass D. density
mass remains unchanged.
500
Which of these is a chemical property of paper? A. The paper does not attract a magnet B. The paper can be crumpled C. The paper can be burned D. The paper is not a good conductor of electricity.
C. The paper can be burned

A rectangular solid has a length of 10 cm, a height of 6 cm, and a width of 5 cm. What is the volume of the rectangular solid?
300 cm3. L x W x H = V
