Question | Answer |
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) |
