What is definite volume and shape?
Solids
Solids Have Definite Shape and Volume: A solid is the state of matter that has a definite shape and volume.
Which phase of matter has a fixed volume but variable shape?
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.
Is volume definite or variable?
The shape and volume of a gas are considered variable. The gas is a state of matter where the atoms are separated from one another, have no definite shape, and has no definite volume.
What is definite volume and fixed shape?
(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.
What is a definite shape?
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 a definite volume?
A liquid has a definite volume but no definite shape of its own. The shape of a liquid changes with the shape of its container. • The particles in a liquid are packed almost as closely together as in a solid. However, the particles in a liquid can move around freely.
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.
Why liquid has definite volume?
Liquids occupy definite volume but have no definite shape. This is because the inter-molecular force of attraction between the molecules in a liquid is less when compared to solids and the liquid molecules are loosely packed. In a liquid, the particles are in close contact and so they have a definite volume.
Is liquid fixed volume and variable 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. The particles can move around.
Is gas a definite shape?
Gases have the following characteristics: No definite shape (takes the shape of its container). No definite volume. Particles move in random motion with little or no attraction to each other.
What do we mean by definite volume?
Definite (for both shape and volume) means that the container makes no difference whatsoever. If 5-liters of liquid water is poured into a 10-liter container, the liquid would occupy 5-liters of the container and the other 5-liters would be empty.
What is an example of a definite volume?
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. Figure 3.3. 2: A Representation of the Solid, Liquid, and Gas States. (a) Solid O2 has a fixed volume and shape, and the molecules are packed tightly together.
Whats definite mean?
: having certain or distinct limits. a definite period of time. : clear in meaning. a definite answer.
Does gas have definite shape?
Gases have the following characteristics: No definite shape (takes the shape of its container) No definite volume. Particles move in random motion with little or no attraction to each other.
What is the shape of a gas?
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have a lower density than other states of matter, such as solids and liquids.
Why gas has no definite shape?
Due to the weak internuclear force of attraction, the gaseous particles have enough kinetic energy and they can move in any direction without any restrictions. Hence, the gases do not have a fixed shape and fixed volume.
What has no definite shape?
Gases have no definite shape or volume.
Is gas shape fixed or variable?
Do gases have a variable shape?
Matter in the gaseous state has both variable volume and shape, adapting both to fit its container. Its particles are neither close together nor fixed in place.
Is liquid a definite shape?
A liquid has a definite volume but no definite shape of its own. The shape of a liquid changes with the shape of its container. The particles in a liquid are packed almost as closely together as in a solid. However, the particles in a liquid can move around freely.
What is the shape of a liquid?
What is the meaning of definite shape?
1 clearly defined; exact; explicit. 2 having precise limits or boundaries. 3 known for certain; sure.
What is a meaning of definite volume?
If the particles of a substance have enough energy to partially overcome intermolecular interactions, then the particles can move about each other while remaining in contact. This describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume.
