What makes each matter unique?
All matter is made from atoms. Every substance (oxygen, lead, silver, neon …) has a unique number of protons, neutrons, and electrons. Oxygen, for example, has 8 protons, 8 neutrons, and 8 electrons. Regardless of the type of molecule, matter normally exists as either a solid, a liquid, or a gas.
Can a solid be poured?
Solids always take up the same amount of space. They do not spread out like gases. Solids can be cut or shaped. Even though they can be poured, sugar, salt and flour are all solids.
Do liquids have a fixed shape?
Because the particles cannot move around, a solid has a fixed shape. Liquids do not have a fixed shape but they do have a fixed volume. The particles are very close together. Most of the particles touch each other.
Do liquids have a fixed temperature?
There is a CHEMICAL difference between the gaseous and liquid state of the same substance. 3. Volume Liquids have a fixed TEMPERATURE, but no fixed shape.
When liquid changes to solid what is called?
Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point.
How can we show that liquid do not have fixed shape?
take about 100ml of water and put it in glass same amount of water in another glass having different shape the water will take different shape i.e.,the shape of glass. This correctly state that a liquid have no fixed shape but have fixed volume. Aakash EduTech Pvt.
Why does a gas not have a fixed shape and volume?
Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.
Why can gases be compressed?
Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles. When a gas is compressed, as when the scuba tank is being filled, the gas particles are forced closer together.
Why do liquids flow?
Liquids flow because the intermolecular forces between molecules are weak enough to allow the molecules to move around relative to one another. In liquids, the intermolecular forces can shift between molecules and allow them to move past one another and flow.
Why do liquid flow in short?
The forces between liquid particles are weaker than the forces between solid particles. This means that liquid particles are further apart and can move about more easily. Since the particles can move, the liquid can flow and take the shape of its container.
