Answer. Answer: When you squeeze it, the solid part changes it shape, but stays the same size. The gas in the holes gets smaller, so the entire sponge takes up less space.

They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas.

Because there is space between the particles, they can be squashed into a smaller volume when the gas is compressed….particles are fixed to near neighbour.

The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

it is called intermolecular spaces are present in between particles of matter.

A gas can be converted into a liquid by increasing the pressure & decreasing temperature. So that the condensation occurs. You must also make the molecules closer so that it is a phase change from a gas to liquid. In liquids, the molecules are very near than that of gases.

During compression, the volume (V) of a gas decreases. When this happens, the pressure (P) of the gas increases if the number of moles (n) of gas remains constant. If you keep the pressure constant, reducing the temperature (T) also causes the gas to compress.

The answer is yes, You can compress water, or almost any material. However, it requires a great deal of pressure to accomplish a little compression. For that reason, liquids and solids are sometimes referred to as being incompressible. You probably have experienced compressing something as hard as steel.

“Compressing water customarily heats it. But under extreme compression, it is easier for dense water to enter its solid phase [ice] than maintain the more energetic liquid phase [water].” Ice is odd. Most things shrink when they get cold, and so they take up less space as solids than as liquids.

Solid is least compressible because the solid is already densely packed so,the solid is incompressible . Liquid is compressible a bit due to its loosely packed structure while gases are highly compressible due to its very loosely packed structure.

Liquids are usually considered incompressible. The molecules are already close together, so it is difficult to compress them any more. Under very high pressures, liquids will actually compress, but not very much.

If energy is continually removed from a liquid, then the liquid freezes to become a solid.

The process of a solid becoming a liquid is called melting. It requires energy for a solid to melt into a liquid. Every pure substance has a certain amount of energy it needs to change from a solid to a liquid. This amount is called the enthalpy of fusion (or heat of fusion) of the substance, represented as ΔH fus.

Going through a phase. Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid).

Matter changes between the liquid and gas states through vaporization and condensation. The change from a liquid to a gas is known as vaporization (vay puh ruh ZAY shun). You can see in Figure 11 that the temperature of the substance does not change during vaporization. However, the substance absorbs thermal energy.

Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization.

Condensation: Gas to Liquid. A. What Is Condensation? Condensation is the change of state from a gas to a liquid.

Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.

The process of sublimation requires additional energy and is therefore an endothermic change. The enthalpy of sublimation (also called heat of sublimation) can be calculated as the sum of the enthalpy of fusion and the enthalpy of vaporization. The reverse process of sublimation is deposition (i.e., gas to solid).

Desublimation is a phase transition in which gas turns into solid without passing through the liquid state. It is the reverse of sublimation. It is how snow forms in clouds, and how frost and hoar frost form on the ground or on windows.

Gas to solid phase transitions are known as “deposition.”…Examples of Gas to Liquid (Condensation)

• Water vapor to dew – Water vapor turns from a gas into a liquid, such as dew on the morning grass.
• Water vapor to liquid water – Water vapor fogs up glasses when moving into a warm room after being in the cold.

Examples of Sublimation:

• “Dry ice” or solid carbon dioxide sublimes.
• Snow and ice can sublime in the winter months without melting.
• Moth balls sublime.
• Frozen foods will sublime and you will find ice crystals inside of the box or bag. Related Links: Examples. Science Examples.

Deposition refers to the process in which a gas changes directly to a solid without going through the liquid state. For example, when warm moist air inside a house comes into contact with a freezing cold windowpane, water vapor in the air changes to tiny ice crystals.

Types of depositional environments

• Alluvial – type of Fluvial deposite.
• Aeolian – Processes due to wind activity.
• Fluvial – processes due to moving water, mainly streams.
• Lacustrine – processes due to moving water, mainly lakes.

Examples include beaches, deltas, glacial moraines, sand dunes and salt domes. In severely cold temperatures frost will form on windows because the water vapor in the air comes into contact with a window and immediately forms ice without ever forming liquid water.

Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
