Knowing the changes taking place in the form of concrete, it’s meaning and examples! –

for example change as things On the other hand, solids can also change shape. But their shape and volume are always the same. Changes in the appearance of solid objects can be in the form of changes in shape or form, followed by changes in the color or smell of the solid object.

Therefore, a change in shape or form must be followed by a change in the color or shape of the solid. Changes in the state of matter can occur spontaneously or through physical and chemical changes.

Changes in solids can be detected on the basis of transformation processes such as melting, sublimation and freezing. The transformation process requires energy and heat.

Below is a description of solid state transitions, along with examples of commonly encountered changes in everyday life:

Change in shape of a solid is the change of one solid object with another shape into another solid. To change the shape of one solid object to another solid requires a special method of transforming it.

It also changes the molecular structure of the solid. Therefore, physical and chemical changes can occur in the form of the solid and replace the chemical elements present in the solid.

Changes in the shape of solid objects cannot chemically restore the original shape of the solid before the change occurred. Below is an example of a deformable solid:

These solids are included in solids because they are dense or molecularly dense, flexible, somewhat rigid and slippery. When the plastic goes through the process of heating.

These objects turned into objects of various shapes, such as buckets, basins, chairs, tables, cabinets, plates, glasses, and many other objects made of plastic. Plastic materials are easy to obtain and the price is cheap.

So you can easily find plastic items. There is no chemical change in this shape change because the chemical elements of the plastic are the same, only the shape differs. Some increase, some decrease.

These exist in the form of solids which are the result of solid changes. That is, wood that has been heated into pulp or paper pulp.

The paper material then goes through several filtering processes to become paper that can be used for writing.

2. Change in form of solid

Change in form is a change in a solid object that changes not only in shape, but also in form. Change of form is the extent to which an object changes from solid to another form, liquid or gas.

Changes in the state of a solid object include physical changes that allow it to return to its original form, and chemical changes that do not return to its original form due to changes in chemical elements.

Below are examples of solid objects that have a change of state that you need to know:

This solid has the properties of a rapidly changing object. The density and shape of this object is like an object that is stored under certain conditions, but it is very easy to change when exposed to energy or heat.

You can see how ice after going through the melting process turns into a liquid when it is left at room temperature which contains heat energy. Ice cubes turn into water.

Its properties differ from those of previous solids, that is, liquids that follow the shape of their container and have no fixed mass and volume. However, there is no chemical change, because the transformation of a snowflake into water is a physical change, only form, not a chemical element.

This item is soft. When this object is heated, it changes shape and becomes more liquid.

Molten margarine changes its shape but does not change its chemical elements, so it participates in physical changes. The elements that make up a solid remain the same after it becomes a liquid.

These solids can be so deformed that they can disappear when placed in large spaces. Instead of being lost, camphor dissolves in air and changes from a solid to a gas.

This may be due to changes in pressure and temperature that can change the shape of the camphor.

This solid nature of camphor also becomes a gas under the influence of the shape of the vessel and the air in the space. Changes in camphor are chemical changes because the chemical elements of camphor mix with air and turn into gas.

Well, this is the explanation of change in shape of solid objects that you need to know. This is because you can find many practical examples of the principle in daily life. You can understand this material in physics reference books.

Books Misconceptions and Concept Change in Physics Education Written by Paul Superno, discusses various problems related to misunderstandings, particularly in the field of physics. Although the theory of transformation into solid, liquid and gas objects is also included. In addition, the principle change as things Which we often face in our daily life.

This book explains what misunderstandings are, some possible misunderstandings, what causes them, how to recognize them and how to overcome them.

Since overcoming misconceptions is always associated with concept change, this book also discusses the theory of concept change and some examples of lessons that help transform a concept from wrong to more right.

Science teachers in general will find this book helpful because there are many similarities between misconceptions in the fields of biology, chemistry, astronomy and natural science.
