|
What are the 3 states of matter? |
Solid, liquid, gas |
|
|
What is the ONLY substance to be found in all 3 states? |
Water |
|
|
Are solids more or less dense than liquids? |
Solids are more dense than liquids |
|
|
Which states of matter take on the shape of the container that they are in?
Choices (can be more than 1) Solids Liquids Gases |
Liquids and gases
Solids retain their shape |
|
|
What thing makes up all matter? |
Atoms or molecules |
|
|
Molecules |
Two or more atoms bonded together |
|
|
In solids, molecules are locked in place, but they are not completely still...they are ______ ? |
Vibrating |
|
|
Why can't the atoms in solids break apart? |
The atoms do not have enough energy to break the bonds holding them together |
|
|
In water, which is more dense, the liquid form or solid form?
Does this apply to all substances, or only water? |
Ice (solid) is less dense than liquid water (so it floats)
This is unique to water |
|
|
Density |
The amount of matter in a given volume |
|
|
What is the density equation? |
D = M/V |
|
|
Is density a physical or chemical property? |
Physical |
|
|
What is the density of water? |
1 |
|
|
Which objects will sink, and which will float in water? |
Objects with a density greater than 1 will sink, and those with a density less than 1 will float |
|
|
How can temperature help change the state of matter from a solid, liquid, and gas? |
Adding temperature adds energy to the molecules so that bonds holding a solid together can begin to break.
The higher the temp -> the more energy -> the more bonds that can break |
|
|
When water (or any substance) changes from one state of matter to another, is this a physical or chemical change? |
A physical change, because it is still a water molecule in all 3 states |
|
|
What are the 3 phases of the water cycle? |
1) Evaporation 2) Condensation 3) Precipitation |
