In a solid there are covalent bonds between atoms. These bonds are created by sharing electrons and are very strong. This prevents the atoms from moving. They are capable of only vibrating in that position.
In a liquid, the bonds are only created by ends of molecules being partially charged. These may be polar bonds when one end has a permanent charge due to an atom having a greater attraction for electrons. The uneven charge distribution creates bonds when ends of molecules with different charges attract each other.
If the molecule is symmetric then dispersion forces create temporary bonds due to a temporary charge distribution as electrons move around. These polar and dispersion forces are not as strong so the bonds break all the time and the molecules may roll around each other.
In gases there aren't any bonds so the molecules just fly and bounce around.
When particles have very less attraction for each other, they tend to move more freely and also that's why the liquids also tend to flow.
A liquids resistance to flow is known as the liquids viscosity. Honey has a high viscosity. Water has a lower viscosity. The slower liquid flows, the higher viscosity is. The viscosity results from the strength of the attraction between the particles of the liquid. For many liquids, viscosity increases as the liquid becomes colder.
What else can I help you with?
How does a gas and liquid flow?
Gases and fluids are all considered fluids which mean they are able to flow. This is because their particles are able to slide into each other. Solids, though some may seem to flow ( salt, sand ) are not able to because their particles are extreamly close together there for they are not able to slide into each other.
Why liquidgas or plasma considered fluids?
Fluids are substances that flow. Liquids flow, gases flow, and ionized gases (plasmas) flow. Thus, they are all fluids.
What can flow from one place to another is it solid liquid or gas?
A gas can flow from one place to another. Liquids can also flow, but solids cannot flow because their particles are closely packed and do not move freely.
Why fluids do not sustain shear stress?
Fluids do not sustain shear stress because they undergo continuous deformation under applied shear forces. Unlike solids that have a defined shape and can resist shear stress, fluids flow and deform when subjected to shear, resulting in no sustained shear stress. This behavior is a fundamental property of fluids known as viscosity.
Why particles of solid do not move at all?
Solids do not flow because particles in a solid are so close together and their forces of attraction are so strong that they cannot flow past one another. If you have a 8th grade Science & Technology Textbook, you can look at page 89 in the second paragraph (Explaining Flow Using Particle Theory) and 2nd sentence, which is your answer that you are looking for (Using the particle theory explain why solids do not flow?)
Is liquid water a fluid?
Any substance that can Flow is called a 'Fluid'. Water is a Fluid Liquid....It can Flow. Steam is a Fluid Gas...It can Flow. Therefore, Liquids and Gases are Fluids. (The Molecules of Solids are closely bonded and cannot move around and over each other. They vibrate in the same position...Solids therefore are not Fluids, they cannot flow). (Norrie wrote this not me so give credit to Norrie)
Why solids are not called fluids?
Solids are not called fluids because solids have a fixed shape and volume, while fluids can change shape and flow to fill the container they are in. Solids have particles that are tightly packed together and vibrate in place, whereas fluids have particles that are able to move past each other.
How does heat flow in solids and fluids?
Either by conduction or convection?
Can a solid flow?
yes indeed solids can flow as well. all states of matter are fluids.
Which state cannot flow from place to place?
solids
Why do fluids liquids and gases flow?
because, unlike solids, they can't sustain shearing stress
What are examples of non fluids?
Some examples of non-fluids are solids (such as ice, wood, and metal) and gases (such as air, oxygen, and carbon dioxide). These substances do not flow and have definite shapes or volumes.
What is the difference between fluids and solids?
Fluids can flow and take the shape of their container, while solids have a fixed shape and volume. The particles in fluids are not tightly packed and can move past each other, whereas the particles in solids are closely packed and vibrate in place. Examples of fluids include water and air, while examples of solids include wood and metal.
Why do solids flow?
Solids do not flow because there is very little intermolecular space between them and hence they hold each other very tightly so they cannot flow
What is the difference about the intermolecular forces of attraction between the phases that allows fluids and gases to flow but prevent solids from flowing?
Fluids and gases have weak intermolecular forces that allow particles to move past each other, enabling flow. In contrast, solids have stronger intermolecular forces that hold particles in fixed positions, preventing flow. This difference in intermolecular forces allows fluids and gases to flow easily, while solids maintain their rigid structure.
Why convection cannot take place in solids?
Convection relies on the movement of fluid particles, such as air or water, to transfer heat. Since solids do not have freely moving particles like fluids, convection cannot take place within them. Heat transfer in solids typically occurs through conduction, where heat is transferred through the vibration of atoms or molecules.
What property do liquids and gases have that solids do not have?
Liquids and gases are able to flow and take the shape of their container, while solids maintain a fixed shape and volume. Liquids and gases are considered fluids due to their ability to flow, in contrast to solids which are rigid and maintain their shape.
