Gas is a state of aggregation of matter in which a substance, under certain conditions of temperature and pressure, has a weak interaction between its molecules and adopts the shape and volume of the resident that contains it, it is a highly compressible fluid. Steam is a type of gas that is always in constant transition between the gaseous state and the liquid.
What is Gas?
Gas is known as a state of aggregation of matter in which, under certain conditions of temperature and pressure, the molecules of a substance interact weakly with each other and do not form bonds. This causes the substance to adopt the shape and volume of the container that contains them and can expand due to their high concentration of kinetic energy.
Gases are highly compressible fluids and undergo density changes with pressure and temperature.
The molecules that make up a gas are not attracted to each other and move in a vacuum at high speed.
Gas is a substance that is in a gaseous state at ordinary temperature and pressure.
What is Steam?
Steam is a state of aggregation of matter in which molecules interact very weakly with each other and do not form molecular bonds, which is why they adopt the shape and volume of the container that contains them.
A vapor is the gaseous form of any substance that can be liquid or solid at normal temperature and pressure.
Differences between gas and steam
- Vapor is a type of gas that is in constant transition between the gaseous and liquid states.
- Vapor is a state of equilibrium between liquid and gas. The liquid can reach the solid state.
- Gas is a substance that cannot become liquid and is a state of matter.
- At room temperature, gas continues to maintain its state. If you want to move to another phase, you must change the temperature and pressure.
