# Does liquid have a definite volume yes or no?

Yes, liquid does have a definite volume. Liquid takes up space and is limited by the size and shape of its container. This means that, unlike a gas, a liquid can not be compressed and is limited to the space available to it in the container.

This means that the volume of a liquid can not be changed, since it is limited by the size of the container it is in. Additionally, since liquids are composed of atoms and molecules that move around and interact with each other, the liquid’s volume will remain consistent over time.

## Can liquid flow yes or no?

Yes, liquid can flow. The ability of a liquid to flow is known as fluidity and it occurs when a liquid changes its level due to gravity and other forces. Fluidity allows liquids to be easily transported and moved by containers, such as pipes and tanks.

In addition, fluidity helps liquids to spread and mix with other materials and substances, creating unique solutions and combinations. For example, water is able to flow across rocks and through the soil, carrying essential minerals with it and allowing them to be absorbed by trees and other plants.

Fluidity also helps achieve an equilibrium by providing an efficient way for liquids to redistribute their mass.

## Why is liquid volume definite?

Liquid volume is definite because it is affected by a number of physical and chemical factors, such as pressure, temperature, and the properties of the liquid itself. A given liquid will always occupy a definite amount of space, as determined by its density and shape.

For instance, if we take a specific volume of a liquid, such as one cup of water, and compress it, its density will increase and it will occupy less space. Conversely, if we increase the temperature of a liquid, its molecules will move faster, occupying more space and thus increasing its volume.

So, no matter what changes are made to the liquid, it will always occupy a definite volume.

## Does gas have a volume?

Yes, gas does have a volume. Many gases can be compressed and take up less volume, or expand and take up more volume, with changes in pressure or temperature. In the context of a closed container, even an empty container has a certain volume associated with it, due to the amount of space taken up by the walls of the container.

If a gas is placed in the container, then the gas will take up some of that space as well. Thus, the volume of the gas can be obtained by subtracting the volume of the walls of the container from the total volume of the container.

## Why do liquids have a fixed volume but not a fixed shape?

Liquids have a fixed volume, but not a fixed shape, because liquids take on the shape of whatever container they are in due to the forces of surface tension. This is known as the Property of Density of Liquids.

This occurs because molecules in liquids are not held together as tightly as molecules in solids, and therefore the molecules can flow freely past each other. This allows the liquid to fill any shape of container it is placed in.

Additionally, liquids are also affected by gravity. The molecules can spread farther apart on the sides of a container than they can on the bottom or top of the container due to the force of gravity.

This phenomenon is known as the Principle of Archimedes. This is why liquids always take on the shape of the container and will not expand or contract when the container’s size is changed.

## Is a liquids volume definite or indefinite?

The volume of a liquid is definitely not indefinite; it has a definite volume. The amount of liquid that can be contained in a vessel or container of a given size is determined by the volume of the liquid and the size of the container.

For example, a liter of water will take up the same amount of space or volume regardless of what vessel it is in, just as 500 mL of water will take up the same volume no matter what size container is used.

This definite volume also allows liquids to be measured and compared by volume. The amount of liquid that fits into a container is a function of the container’s volume, not the liquid’s–keeping the liquid’s volume definite and constant.

## Can a gas ever have zero volume?

No, a gas can never reach a volume of zero because the physical laws governing the behavior of gases prevent it. At very low temperatures, molecules can slow down to a point where their motion approaches zero, but their volume cannot.

Under ideal conditions, a gas can reach a state of very low density, but it still occupies some finite volume. As the pressure and volume of a gas approach zero, the temperature must also tend to zero, which makes it impossible to actually reach a zero volume state.

## Why does a gas have no volume at absolute zero?

At absolute zero (0 Kelvin, or -273. 15 Celsius), the kinetic energy of particles in a gas is also at zero. Because of this, the particles virtually cease to move or react with each other, and thus the gas has no volume.

This lack of kinetic energy causes the particles to collapse into a small space, making those particles virtually immobile. As a result, particles are unable to move and expand the volume, making the volume of the gas zero.

In addition, the lack of movement and reaction between particles means that the gas is essentially in a state of suspended animation.

## At what condition does the volume of a gas become zero?

The volume of a gas becomes zero when it undergoes an isothermal compression leading to a state known as the Boyle-Mariotte law, which states that in order for the volume of a gas to become zero, the absolute pressure must become infinite.

This can be achieved when a gas is forced into a closed container and compressed until the gas molecules become so close together that their motion is restricted. This phenomenon is known as a fluid undergoing an isothermal (constant temperature) compression.

The pressure exerted by the gas increases as the molecules press against each other, eventually becoming so great that the volume drops to zero. At this point the temperature and pressure within the container become very high and are referred to as the Critical Point.

This state is impossible to achieve in practice, as pressures and temperatures at the critical state are so high that the container would break apart before enough pressure could be generated for the volume to reach zero.

## Does air freeze at absolute zero?

No, air cannot freeze at absolute zero. The temperature of absolute zero is -273. 15°C, which is the lowest theoretically possible temperature. In order for air to freeze it needs to reach a temperature of about -195.

8°C, a temperature about 77. 4°C lower than absolute zero. This means that no matter how far below the temperature of absolute zero that the air reaches, it will not freeze.

## What happens to gas at 0 Kelvin?

At 0 Kelvin, or -273. 15 degrees Celsius, all substances, including gases, will reach their highest level of entropy and become an unstructured state. In this state, all the atoms or molecules in a gas will spread as much as possible, all traveling at different speeds in different directions and occupying the space they are in evenly.

At this temperature, gases would also become solid and form a crystalline material – though this substate, called solid-state sublimation, would likely occur very slowly. The pressure of the gas would remain the same as it was at 0 Kelvin, but its volume would shrink.

To reach 0 Kelvin, gases will need to be cooled to close to absolute zero, the coldest temperature that is theoretically possible, with no heat energy remaining.
