“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.

A gas and a liquid will change shape to fit the shape of their container. A gas will change volume to fit the volume of the container. In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them.

Liquids are always considered to be incompressible fluids, as density changes caused by pressure and temperature are small. While intuitively gases may always seem to be incompressible fluids if the gas is permitted to move, a gas can be treated as being incompressible if its change in density is small.

Compressibility can be defined as the proportional reduction in the thickness of a material under prescribed conditions of increased pressure or compressive loading.37.

Air still takes up space, but the amount of space it takes up can change when it is squeezed or compressed in a closed system. (Sealing the opening of the syringe changes it temporarily into a small closed system.) Air can’t be squeezed so much that it takes up no room at all.

Answer. It takes longer to boil water than to melt ice because of the difference in the amount of heat required to overcome the forces of attraction by keeping the temperature constant during this time.

Boiling on the other hand, requires much more energy and therefore does require some input. Boiling occurs much faster than evaporation but requires more energy. Define melting point. Melting point is the point at which a substance starts to change from a solid to a liquid.

As with melting, the amount of energy needed to vaporize a substance is proportional to the amount of substance present. The more liquid there is, the more energy required to vaporize it….Enthalpy.

Latent heat is the heat energy required to change a substance from one state to another. Energy is required to change from solid to liquid, liquid to gas (evaporation), or solid to gas (sublimation). Energy will be released to change from liquid to solid (fusion), gas to liquid (condensation), or gas to solid.
