There are 2 types of fluids. Gas and Liquid.
The process in which a liquid changes into a solid is called freezing. The particles loses kinetic energy, therefore the forces of attraction at the nucleus of the particles pull the particles more closely together. When a liquid changes completely into a solid, the particles will be very closely packed, and cannot move freely at all. An example would be the freezing of water into ice.
The process in which a gas in changed to a solid is called desublimation, or deposition. Most elements have 3 states of matter (solid, liquid, gas). With that said, a gas usually condenses (loses kinetic energy, the particles becomes more closely packed) to become a liquid, before undergoing the freezing process to change into a solid. However, some elements can skip the liquid phase and directly become a solid. This is affected by the pressure exerted on the gas. Under high pressure, water vapour for example can desublime into ice without first becoming water. This is how snow is formed.
melting
A change of state is a change in the object from a solid to a liquid. Other changes of state are a solid to a gas or from a liquid to a solid.
solid to a liquid
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
These are changes in physical state, which are physical changes.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
The freezing point is when a liquid changes into a solid.
1) melting-solid state changes into liquid state and 2)freezing-liquid state changes into solid state
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
This phasechange is called as melting.
more energy, for the most part heat, changes the state between solid and liquid.
melting
A liquid will change to a solid when it freezes.
A change of state is a change in the object from a solid to a liquid. Other changes of state are a solid to a gas or from a liquid to a solid.
The 5 changes of state are melting (solid to liquid), evaporation (liquid to gas), condensation (gas to liquid), freezing(liquid to solid), and sublimation (solid to gas or gas to solid)
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
