Conditions for LPG liquefaction:
- Low temperature and high pressure:
- LPG can be liquified at a low temperature and high pressure.
- When the temperature is lowered and the pressure is increased, the gas molecules come closer together, leading to liquefaction.
- For example, at a temperature of around -42°C and a pressure of about 8 bar, LPG can turn into a liquid state.
Explanation:
LPG (Liquefied Petroleum Gas) consists of a mixture of propane and butane gases. In order to convert these gases into a liquid form, specific conditions of temperature and pressure need to be met.
When the temperature is lowered and the pressure is increased, the gas molecules lose energy and move closer together, eventually forming a liquid. This process is known as liquefaction. Therefore, in the case of LPG, a combination of low temperature and high pressure is required for the gas to turn into a liquid state.
By maintaining the correct set of conditions, LPG can be stored and transported more efficiently in its liquid form, making it easier to handle and use in various applications such as heating, cooking, and fuel for vehicles.
