What makes up all matter? | atoms
🗑
|
||||
true or false - atoms are in constant motion | true
🗑
|
||||
what is the relationship between temperature and motion of atoms | the warmer (more thermal energy) the atoms are (have), the faster they are moving
🗑
|
||||
What is not made of matter? | energy - electricity, heat, light, sound, etc.
🗑
|
||||
Describe the motion of atoms/molecules in a solid | they atoms are vibrating in place
🗑
|
||||
Describe the motion of atoms/molecules in a liquid | the atoms are moving faster than in a solid - the bonds between the atoms/molecules are not as strong.
🗑
|
||||
Describe the motion of atoms/molecules in a gas. | the atoms are moving the fastest of all three states
🗑
|
||||
solid | a substance that has a definite shape and volume
🗑
|
||||
liquid | a substance that has a definite volume, but not a definite shape - it takes the shape of its container
🗑
|
||||
gas | a substance that has no definite shape or volume
🗑
|
||||
condensation | phase change from gas to liquid
🗑
|
||||
melting | phase change from solid to liquid
🗑
|
||||
boiling | phase change from liquid to gas
🗑
|
||||
freezing | phase change from liquid to solid
🗑
|
||||
sublimation | phase change from solid to gas (skipping liquid phase)
🗑
|
||||
how does the motion of molecules change during melting? | the molecules are vibrating so fast from the increased thermal energy in the environment that they break free from their fixed positions.
🗑
|
||||
How does the motion of molecules change during freezing? | The substances loses energy to the environment causing them to move more slowly - so slowly they stick together in fixed positions
🗑
|
||||
How does the motion of molecules change during condensation? | the molecules lose energy to the environment causing them to move more slowly and start to stick together in the form of a liquid
🗑
|
||||
How does the motion of molecules change during boiling? | the increase in energy from the environment causes the molecules to move so quickly where they break free from each other and become a gas
🗑
|
||||
How does the motion of molecules change during sublimation? | substance gains so much energy from environment that the particles vibrate so much they break free of each other and become a gas (skipping the slower moving liquid phase)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
