Each type of object has its own properties and characteristics that allow it to experience different forms of change. The shape of this object changes depending on the conditions that affect it.
These changes can vary because each substance also has its own characteristics that require a separate transformation process. You may easily find changes in the shape of these objects in everyday life.
Changes in the Form of Things
Below are various changes in the shape of objects that need to be known to maximize their environment for daily needs:
1. Melt
Melting is a type of state change that occurs in a solid to a liquid. This change requires heat or heat that affects the substance. This change in state of matter is also referred to as melting.
An example of changing the state of melting is for example, you melt candy to thicken it by heating it on the stove. You can also see the simplest example in the change in melting ice cubes.
2. Freezing
Freezing is a physical change that occurs in a liquid to a solid. The change in freezing is almost the opposite of thawing.
This means that at cold temperatures, the change-of-state process caused by freezing releases heat, not melting. You can see an example of this change in shape when making ice cubes.
In accordance properties of liquids that follows the shape of the container, you can make ice cubes in various shapes when you have compacted them in the freezer.
3. Yawning
Evaporation is a state change that occurs in a liquid to a gaseous substance. Evaporation is a change of state that requires heat or heating.
These changes do not only occur in liquids, but can also occur in the human body. For example, when we sweat, the sweat evaporates and cools our bodies. Most often we see boiling water, as it boils it gives off steam.
4. Condensing
Condensation is a type of change that occurs from a gas to a liquid. It occurs in gases in cold air or at low temperatures down to water droplets. This state change is involved in processes that release heat because they require low temperatures.
You might see dew on grass leaves in the morning, or a glass that has condensed from being filled with cold water or ice cubes.
5. Sublimation
Sublimation is a change that occurs from a solid to a gas. The conversion process by sublimation requires heat or heat energy, so that solid objects can change air molecules into gas molecules.
For example, if camphor is brought into a room, its solids will reduce over time as it sublimes into the air.

6. Crystallize
Crystallization is a state change that occurs in a gaseous material into a denser material. This process of changing shape depends on the release of heat or heat energy at a lower temperature than the object.
You can see this change in the jar of honey, where crystallized sugars form over time.
Causes of Changes in the Form of Things
Changes in the form of objects are of course not without cause, therefore, so that with changes in their form there are symptoms that can be detected directly or with the help of tools.
This change in shape can be caused by changes in the physical, chemical and biological properties of a substance as follows:
1. Physical Changes
Physical change is a form of change in the substance of an object that can be seen or felt by the naked eye only by its physical appearance or appearance.
Therefore, a change in physical form does not change the chemical composition of the object. These changes in no way change matter or create new matter.
The characteristics of the nature of this change are visible and recognizable from the outside or physical changes and can return to their original state before the material changed.
2. Chemical Changes
Chemical change is a change in the shape of an object that occurs in the shape and size of a substance so as to produce a new, different substance.
This shape change results in different or new types and properties of the fabric material compared to the original fabric. Chemical reactions produce substances or compounds that change into new chemical formulas.
In practice, a chemical change experiences material shrinkage as it changes. Chemical changes can occur through combustion, cooling, heating, decomposition and corrosion.
3. Biological Changes
Biological change is one of the changes that occur due to the actions of other living things or decaying microorganisms.
Like chemical changes, biological changes cause irreversible changes to matter. You will find examples of biological changes that change the shape of wood due to weather and then begin to decompose.
