Liquid State vs Gaseous State
Liquid state and Gaseous state are two states of matter that show great differences between them. A substance boils into a gas at its boiling point whereas the substance melts into a liquid at its melting point. This is the main difference between the two states.
It is important to know that the liquid state of a substance is characterized by a definite volume, but it does not have a definite shape. On the other hand it takes the shape of the vessel or the container that holds it. On the other hand a pure gas in its state is made up of individual atoms, elemental molecules or compound molecules.
It is interesting to note that the gaseous state of matter exists between the liquid and the plasma states. The plasma state is the state characterized by the upper temperature limit for gases.
One of the principal differences between the two is in terms of the method or the properties by which you can sense them. The liquid state can be sensed quite differently form the way gaseous state can be sensed.
Chemists have found that gaseous state can be sensed by means of the properties that are four in number. They are the physical properties such as pressure, volume, number of particles and temperature. Various chemists in the past have found out these different properties of gases.
On the other hand the liquid state can be quite easily sensed by perception. It is to be understood that some of the most familiar liquid states at room temperature are benzene, water, alcohol, castor oil, corn oil, carbon tetrachloride and gasoline.
The ability of the liquid to flow is measured in terms of its viscosity. Viscometers are used presently to measure the viscosity of various liquids. On the other hand various laws were stated in connection with the properties of gases. These laws include Boyle’s law, Avogadro’s law and Dalton’s law.
Physicists would call glasses though they are solids as frozen liquids. This is because of the fact that the arrangement of the molecules in the substances such as glasses is very much the same as in liquid state. Physicists classify gas models and widely discuss them as perfect gas, ideal gas and real gas. Each of these models exhibit different properties. They found out that gas particles move about freely in the absence of an applied electric field.
