Different
objects can be made of different types of materials (the matter from which
objects are made). For example, a cupboard is made of wood, nails, etc. The Ответ of the materials will affect the properties
of the object. In the example of the cupboard, the strength of the wood and
metals make the cupboard strong and durable. It is very important to understand
the properties of materials, so that we can use them in our homes, in industry
and in other applications.
