|
What are particles like in a solid |
Very close together, regular pattern, vibrate in a fixed position, low energy |
|
|
What are particles like in a liquid |
Close together, randomly arranged, move around each other, greater energy |
|
|
What are particles like in a gas |
Far apart, randomly arranged, move quickly in all directions, highest energy |
|
|
What are solids like |
Fixed shape and cannot flow because their particles cannot move, cannot be compressed because their particles are close together and gave no space to move to |
|
|
What are liquids like |
Flow and take the shape of their container because their particles can move around each other, cannot be compressed as their particles have no where to move to as they are close together |
|
|
What are gases like |
Flow and completely fill container because their particles can freely move, can be compressed as their particles are far apart and can move |
|
|
What is it called when a gas turns into a solid without becoming a liquid first (or vice versa) |
Sublimation |
|
|
In which reactions does energy get transferred from the substance to the surondings |
Condensation and freezing because the forces of attraction between atoms in stronger |
|
|
Why is energy transferred to a substance to change its state (melting, evaporating, boiling) |
To break some of the bonds between the particles (melting), or to overcome the remaining forces of attraction between particles (evaporating and boiling) |
