Why does solid maintain its shape?
A solid is in a state of matter that maintains a fixed volume and shape. A solid’s particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with definite volume.
Do solids take the shape of their container?
A solid will retain its shape; the particles are not free to move around. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
Which matter takes the shape of its container?
Which matter has no definite shape?
Why liquid has no definite shape?
In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
Do liquids have definite shape?
Liquids have the following characteristics: no definite shape (takes the shape of its container) has definite volume. particles are free to move over each other, but are still attracted to each other.
What is the process called when a solid turns into a liquid?
The process of a solid becoming a liquid is called melting. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance. It requires energy for a solid to melt into a liquid.
How can we show that liquid do not have fixed shape?
Liquids do not have a fixed shape but a fixed volume because of the fact that the inter molecular force which the molecules exert on each other is not that strong and so a liquid takes the shape of the container it is poured in. The free movement of molecules between the particle spaces is a main feature of liquids.
Can liquids change shape?
Liquids can flow or be poured easily. They are not easy to hold. Liquids change their shape depending on the container they are in. Even when liquids change their shape, they always take up the same amount of space.
Does diffusion happen faster in a liquid or a gas?
Diffusion in liquids is slower than diffusion in gases because the particles in a liquid move more slowly. It happens faster if the temperature is increased.
Why diffusion is faster in gases than liquids?
The molecules of gas have more kinetic energy than liquid molecules and are smaller. The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids. Therefore, gas particles have higher kinetic energy and travel more rapidly.
Why does diffusion occur in gases?
Gaseous particles tend to undergo diffusion because they have kinetic energy. Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Effusion refers to the movement of gas particles through a small hole.
What is the diffusion of gases?
Gaseous atoms and molecules move freely and randomly through space. Diffusion is the process whereby gaseous atoms and molecules are transferred from regions of relatively high concentration to regions of relatively low concentration.
Who worked on diffusion of gases?
Under what conditions of temperature and pressure a real gas behaves like an ideal gas?
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles’ kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
What is the Graham’s law of diffusion?
Graham’s law is an empirical relationship that states that the ratio of the rates of diffusion or effusion of two gases is the square root of the inverse ratio of their molar masses.
