What is matter? Choose the best answer.
Anything that is solid
Anything that takes up space and has mass
Anything that has a fixed volume
Anything that can be seen
In what way are liquids different from solids?
Liquid molecules are lighter than solid molecules.
Liquids are made of atoms; solids are made of molecules.
Liquids don't have a fixed shape; solids do.
Liquids are always denser than solids.
What happens to the chemical structure of water when it changes state?
Water molecules break apart to form individual atoms.
Water molecules harden into ice molecules.
Water molecules melt into gas molecules
Nothing happens to the chemical structure.
What will happen if you keep increasing the temperature of a liquid?
It will boil and become a gas
It will transpire
It will remain a liquid
It will solidify
What do lightning and stars have in common?
Both have no electrical charge
Both contain plasma
Both have a fixed volume
Both contain all three states of matter
Water's chemical formula is "H2O." What does this mean?
Water is composed of hydrogen molecules and oxygen molecules.
A gram of water contains 20 hydrogen atoms.
Each water molecule contains two hydrogen atoms and one oxygen atom.
Water molecules cannot be split into smaller pieces.
What is the basic shape of a liquid?
A sphere
The same shape as a gas, only rounder
A cube
Whatever shape its container is
How can you remove energy from matter?
By increasing its volume
By lowering its temperature
By increasing its pressure
By boiling it
Gases have a tendency to expand. What's the best synonym for "expand?"
Collide
Spread out
Shrink
Boil
What are the three main states of matter?
Solid, liquid, and gas
Ice, water, and steam
Temperature, pressure, and energy
Hot, cold, and warm
Compared to ice, how do molecules of water behave?
They move less freely
They are locked into a crystal lattice
They move more freely.
They bounce off one another randomly.
What do water vapor, liquid water, and ice have in common?
The same crystal lattice structure
The same amount of energy
The same physical properties
The same chemical properties
What's the easiest way to add energy to matter?
Heating it
Cooling it
Decreasing pressure
Decreasing temperature
How do the molecules of a gas behave?
They vibrate in place
They are very loose particles that spread out to fill a space.
They are locked in a crystal lattice
They clump together
If you put a thermometer into a pot of melting ice, when will the temperature rise past zero degrees Celsius?
As soon as the ice begins to melt.
After most of the ice has melted.
When the ice begins turning into steam.
When all the ice has melted.
If a substance has a large mass and a small volume, what can you conclude about it?
It's very dense
It will float on water
It is made out of rock or metal
It has a low density
What is the difference between weight and mass?
Weight depends on density and mass depends on gravity.
Weight depends on gravity and mass depends on volume.
Mass depends on gravity and weight is constant.
Weight depends on gravity and mass is constant.
If you wanted to measure an irregular object's volume, which of the following devices could you use?
What is always true of an object with a lot of mass?
It contains a lot of matter
It has a large volume
It has a high density
It cannot be accurately measured
If an object's mass is 50 g, and its volume is 10 cubic cm, what is its density?
500 g/cubic cm
5 g/cubic cm
60 g/cubic cm
40 g/cubic cm
