  Argon liquid to gas expansion ratio
  The expansion ratio of a substance refers to the ratio of the volume of the gas to the volume of the liquid from which it was formed. For argon, like other gases, this ratio can be quite large because liquids are generally much denser than gases at the same temperature and pressure.
  The expansion ratio of argon as it transitions from liquid to gas at its boiling point (87.30 K or -185.85°C) and 1 atmosphere of pressure is approximately 860:1. This means that one liter of liquid argon will expand to about 860 liters of gaseous argon under standard conditions.
  It’s important to note that this is an approximate value, and the actual expansion ratio can vary depending on the specific conditions of temperature and pressure during the phase change.
  Is liquid argon flammable？
  liquid argon is not flammable. Argon is an inert gas, which means it is chemically non-reactive under normal conditions. It does not support combustion or react with most substances, which is why it is often used in environments where it is important to prevent chemical reactions, such as in some types of manufacturing processes or in lighting where an inert atmosphere is desired to protect the filament from oxidation.
  However, it is important to note that while argon itself is not flammable, it can displace oxygen in an enclosed space, which can create a hazardous environment for humans and other organisms that require oxygen to breathe. Always handle argon, in both its liquid and gaseous forms, with appropriate safety measures in place.
