What is a MIXTURE?
Combining two or more types of matter that can be easily separated.
Gases have a specific shape?
False. Gases spread out to fill their container.
Solution.
What are the three states of matter?
Solid, Liquid, and Gas
How can you tell if an object is more dense when combining two types of matter?
The most dense object will sink. The least dense object will float.
What is displacement?
When an object is placed in liquid, it will push the liquid out of the way causing "displacement".
Solids have a specific shape.
True.
Is baking a cake an example of a physical or chemical change?
Chemical
Is the water cycle an example of a chemical or physical change?
Physical.
How do you measure the volume of a rectangular 3-dimensional object?
What is mass?
The amount of material that makes up a piece of matter.
The particles in a liquid keep its own shape no matter what container it is in.
False. Liquid particles move to fit the container they are in.
Mixture.
A rock will sink when it is placed in syrup. This is because the rock is (more/less) dense than the syrup?
More.
What tools are needed to measure mass?
A balance scale.
What is a property?
A property is something that can be observed or measured and is used to describe matter.
A solution is combining two or more types of matter that can easily be separated.
False. Solutions cannot be easily separated.
A rusting bicycle is an example of a physical or chemical change?
Chemical.
What is the BOILING point of water?
100 degrees Celcius.
What tool is needed to measure the volume of an irregular solid?
A graduated cylinder.
What is density?
Density is the amount of mass in a certain volume.
Two objects that have the same volume will have the same weight.
False. Two objects of the same volume could have different weights depending on the type of matter they are.
Cutting hair is an example of a chemical or physical change?
Physical.
What is the FREEZING point of water?
0 degrees Celcius
Describe the difference between mass and weight.
Weight is the measurement of Earth's gravitational pull on an object. It can fluctuate based on gravity. Mass is the amount of matter inside of an object. It is constant and does not change.
