Question

What are the properties of a solid?
A.A state of matter that has a definite volume but not a definite shape.
B.A state of matter that does not have a definite volume or shape.
C.A state of matter that has a fixed volume and shape.
D.A state of matter that conducts electricity well.
E.A state of matter similar to gas that has free electrons.

Answer 1

Hint: Solids are those states of matter which have definite shape and definite volume. Fixed shape means if we place them in any container then their shape will not change. It will be the same as before. In solids molecules are closely packed.

Complete step by step answer:
There are mainly three states of matter known as: solids, liquids and gases.
Solids: Solids are those states of matter which have definite shape and definite volume. Fixed shape means if we place them in any container then their shape will not change. It will be the same as before. In solids molecules are closely packed.
Liquids: Liquids are those states of matter whose atoms or particles are held together by intermolecular force which is less than that of forces in solids. Liquids have definite volume but not have definite shape i.e. they will take the shape of the container. For example: if we place them in cylindrical vessel then they will look like cylindrical shape.s
Gases: Gases are those states of matter whose atoms or particles are held together by a very weak force of attraction i.e. vanderwaal force of attraction which is less than that of forces in solids and in liquids. Gases do not have definite volume and do not have definite shape. They move in the whole container in which they are placed. As they have a very weak force of attraction hence they occupy more space because they randomly move everywhere in the space.

Hence by looking at the options it is clear that option C is correct i.e. those states of matter which have definite shape and volume.


Note:
The state of matter that conducts electricity is plasma. Plasma is the same as gases. We can say plasma is a subset of gases. But there is a slight change in their properties. Plasma are made up of atoms in which some or all the electrons are stripped away and positively charged nuclei, called ions, move freely.
