20 Examples from Liquids to Solids (and the other way around)

All matter It can be in three physical states: solid, liquid or gaseous (although there is a fourth state, the plasmatic). A substance can change from one state to another (from solid to liquid, from liquid to gaseous, from gaseous to solid or vice versa) when exposed to changes in temperature and pressure.

These changes of state modify the volume of the substances, since they generally expand through the heating and they contract on cooling, but they do not entail changes at the chemical level but only physical.

The phenomena that occur when matter passes state solid to liquid and vice versa They are:

The difference between the states of aggregation of matter is given by the closeness or distance that exists between the particles that make up that substance. Due to this closeness, the cohesion forces (attractive forces) between the particles will be higher or lower and that, among other factors, will determine the state of aggregation of a certain substance.

Matter in a liquid state (intermediate cohesion) has a defined volume but not a fixed shape; solid matter (higher cohesion) has a defined shape and the particles are together; matter in the gaseous state (less cohesion) expands freely and does not have a defined volume or shape.

Examples of transition from liquids to solids (solidification and freezing)

1. Fruit juices - ice cream
2. Ice water
3. Milk - frozen milk
4. Honey - crystallized honey
5. Alcohol - solidified alcohol
6. Mercury - solidified mercury
7. Lava - volcanic stone

Examples of transition from solids to liquids (melting)

1. Ice water
2. Sugar - caramel
3. Glass - liquid glass
4. Chocolate - melted chocolate
5. Cheeses - melted cheese
6. Butter - melted butter
7. Candle - liquid paraffin
8. Plastics - liquid plastics
9. Metals - molten metals
10. Grease - liquid fat
