What is the importance of phase changes in our environment? Give some concrete examples.

Answer:

A phase change is a transition of matter from one state to another. Phase changes occur regularly in nature and can be conducted by people. The phase in which matter exists is determined by the pressure and temperature of its surroundings. By manipulating the pressure and temperature, you can change the phase of the matter.

They occur because thats just how physics works. There isnt anything profound going on. Lets take water as an example. Water boils because enough energy has been introduced into the system such that molecules are able to break away from the interactions keeping them in the liquid state.

Types of Phase Changes

  • Freezing occurs when a liquid changes to a solid.
  • Melting occurs when a solid changes directly to a liquid.
  • Sublimation occurs when a solid changes directly to a gas.
  • Deposition occurs when a gas changes directly to a solid.
  • Condensation is when a gas changes directly to a liquid.
  • Vaporization happens when a liquid changes directly to a gas.
  • Ionization occurs when a gas changes to plasma.
  • Recombination occurs when plasma changes to gas.

When a pot of water is placed on a burner, it will soon boil. A phase change is occuring. The liquid water is changing to gaseous water, or steam. On a molecular level, the intermolecular forces between the water molecules are decreasing. The heat is providing enough energy for the water molecules to overcome these attractive forces.
