Superheated Vapour
Definition:
Superheated vapour is a state of a substance where its temperature is higher than its boiling point at a given pressure. It is a completely gaseous state and is used in various applications such as power generation, refrigeration, and air conditioning.
Behaviour of Superheated Vapour
Superheated vapour behaves approximately as a gas. This means that it follows the gas laws, such as Boyle's law, Charles' law, and the ideal gas law. However, there are some differences between superheated vapour and an ideal gas, such as:
- Superheated vapour has a higher specific heat capacity than an ideal gas. This means that it requires more heat to raise its temperature by one degree Celsius.
- Superheated vapour has a lower density than an ideal gas. This means that it occupies more space at the same temperature and pressure.
Applications of Superheated Vapour
Superheated vapour is used in various applications such as:
- Power generation: Superheated steam is used to drive the turbines in thermal power plants.
- Refrigeration: Superheated refrigerant vapour is used in refrigeration systems to absorb heat from the surroundings.
- Air conditioning: Superheated vapour is used in air conditioning systems to cool the air.
Conclusion
In conclusion, superheated vapour behaves approximately as a gas and is used in various applications such as power generation, refrigeration, and air conditioning.
