Do solids have fixed volume?
have a fixed volume and a fixed shape. cannot be compressed , because their particles are close together and have no space to move into.
Does a solid have a fixed or variable volume?
Matter in the solid state maintains a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place. Matter in the liquid state maintains a fixed volume, but has a variable shape that adapts to fit its container. Its particles are still close together but move freely.
Why solid has a fixed volume?
(a) Solids have definite shape and definite volume because the molecules in solid are closely packed and in fixed positions. The molecules can vibrate but do not move around which keeps the shape and volume definite.
Do solids have the same volume?
Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
What is the volume of a solid?
The volume of a solid is the measure of how much space an object takes up. It is measured by the number of unit cubes it takes to fill up the solid. Counting the unit cubes in the solid, we have 30 unit cubes, so the volume is: 2 units⋅3 units⋅5 units = 30 cubic units.
What is a fixed volume?
Fixed volume is the property of liquid and solid. Which shows that the volume of both solid and liquid remain fixed under fixed temperature and pressure. Unlike gases, where the volume changes without applying any external force.
Do solids have a fixed or variable shape?
Solids have a fixed shape and a fixed size. The particles are very close together and held in place by strong forces (bonds). Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape.
What is a solids volume?
What is fixed volume?
What is the volume of a solid sphere?
The formula for the volume of a sphere is V = 4/3 πr³.
How do you find the volume of a solid cylinder?
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . Simplify.
Why do solids have a fixed shape Why do gases follow the shape of the container they are in?
Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape. The particles move around all the time and spread out. This is why a gas fills its container.
Why do solids have definite shapes and volumes?
Solids have definite shapes and volumes because their atoms and molecules are held together firmly by the strong inter-molecular forces. At low temperatures, the kinetic energy in the solid is usually not enough to overcome these intermolecular forces, so the solid remains in the same state.
Why do liquids have fixed volume but no fixed shape?
LIquid have fixed volume but not the fixed shape because it has less force of attraction . It is the property of liquids. The molecules of the liquids are loosely bound. So, the liquid can take the shape of the container. But the volume of the liquid is fixed.
Does solid have a definite volume?
Solids have a definite shape and definite volume. This means the shape of the material does not change, and it can’t be compressed. Liquids do not have a definite shape, but have a definite volume. This means that a liquid will take the shape of whatever container it is in, but the liquid can’t be compressed.
Does a gas have a definite volume?
A gas does not have a definite volume. By its definition, a gas is a fluid state of matter that fits to the shape and volume of its container.
