Difference between Gas and Steam Turbine

Many people mistakenly believe that gas and vapor are the same, ignoring that they are very different substances. There are four states of matter: liquid, solid, plasma, and gas. This last state occurs when there is a lot of space between the molecules, thus allowing them to move in different directions and constantly expand.

Taking into account what we have said above about the gaseous state, below we will tell you what differentiates gas from vapor.

STEAM Difference between Gas and Steam Turbine

Vapor is a type of gas, but at all times it is in constant transition between the gaseous state and the liquid. It is a gas when it is below its critical temperature, but it can be condemned as a liquid by increasing its pressure without reducing its temperature.

Vapor can also be described as a state of equilibrium between the liquid and the gaseous. In addition to being liquid, its state can become solid.


On the other hand, a gas is a substance that cannot become a liquid simply by applying pressure to it. Unlike vapor (and as you may have noticed after reading the introduction) one of the states of matter is gaseous, but we do not speak of a “vaporized” state.

At room temperature the gas will remain gas in its natural state. If you want to change this phase, then it is necessary to change both the temperature and the pressure.

Finally, gases can be easily compressed, but not as easily as vapor; since the latter is in a constant state of transition. When a gas is put in a container, it fills it and takes up more space than substances in a liquid or solid state.

Vapor particles can have a definite shape when viewed under a microscope, as opposed to gas particles that have no definite shape.
