👉 Condensance is a property of gases that describes how well they can be condensed into liquids or solids. It is typically measured in terms of the degree to which the temperature and pressure are increased, as a result of condensation, compared to the initial state. Condensation occurs when an ideal gas (like water vapor) is heated up to its boiling point, causing it to condense into smaller droplets or ice crystals that can be separated from the original gas by cooling down.
