Boiling

Liquid
Solid
Melting
A physical change from solid to liquid phase and happens only at a specific temperature.
The phase of a substance that has volume and shape. It is incompressible and particles are tightly packed.
Phase of a substance that has volume, and takes the shape of it's container. Particles are slightly spread apart from each other.
Phase of a substance that has no volume or shape, but will take it of the container. Particels are spread very far apart from each other.
Physical change from liquid to solid phase and happens only at a specific temperature. A synonym of Boiling is vaporizing or evaporating.

For Mindful Monday, Here are some fun facts:
90% of the information we assimilate is received through sight and, what’s more, we retain 42% more information when the content moves.
Interactivity and animation can be your best allies when creating tables, infographics, or graphs that help provide context for the information and simplify the data in order to communicate it to your audience. We are visual beings and we find it easier to ‘read’ images than to read a written text.

Boiling/Vaporize = Condensation
Liquids
A physical change of the opposite of liquid to gas, which is gas to liquid and only happens at the specific temperature
Synonym of Melting = Freezing
- The particle diagram shows the liquid phase and the features of a substance in the gas phase:
- form of matter that flows
- has constant volume
- takes the shape of its container
- less closely packed than particles in solids.
A physical change of the reverse of solid to liquid phase, which is liquid to solid and happens only at a specific temperature.
Gas
Solid
- The particle diagram represents the gas phase and features of a substance in a gas phase is:
- compared to the other states the particles are far apart
- 'expand' to uniformly fill the entire volume of the container
- Particles are far apart gases are easily compressible
- The particle diagram represents the solid phase and features of a substance in a solid phase is:
- definite shape
- definite volume
- expands slightly when heated
- does not take shape of its container
- particles are tightly packed and are incompressible
