Definitions
- Referring to a gas or mist that is visible, such as water vapour. - Talking about the process of evaporation or condensation. - Describing a substance that is in a gaseous state at room temperature and pressure.
- Referring to the gas or mist that is produced when water is boiled. - Talking about the power generated by steam engines. - Describing the process of cooking food using steam.
List of Similarities
- 1Both vapour and steam refer to a gaseous state of matter.
- 2Both can be produced by heating a liquid, such as water.
- 3Both can be used for various purposes, such as cooking or generating power.
- 4Both are invisible when they are at normal temperature and pressure.
What is the difference?
- 1Source: Vapour can come from any substance that can evaporate, while steam specifically refers to water vapour.
- 2Temperature: Steam is hotter than vapour, as it is produced by boiling water.
- 3Density: Steam is denser than vapour, as it contains more water molecules per unit volume.
- 4Visibility: Steam is visible, while vapour may or may not be visible depending on the substance and conditions.
- 5Usage: Steam is often used for power generation and cooking, while vapour is used in various scientific and industrial applications.
Remember this!
While both vapour and steam refer to a gaseous state of matter, they have some key differences. Vapour can come from any substance that can evaporate, while steam specifically refers to water vapour produced by boiling water. Steam is hotter and denser than vapour, and is often used for power generation and cooking, while vapour is used in various scientific and industrial applications.
