When it comes to air con, Perth residents rely on their system to keep their homes comfortable. This is especially true during the peak heating and cooling periods. When a problem occurs, it always seems to happen at the worst possible times. Additional strain during these times of the year can cause excessive wear and tear. This will make your AC system more prone to failing and less energy efficient. Regularly scheduled maintenance can certainly help to ensure that your AC system is working efficiently.
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon),elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. One type of commonly known gas is steam.
