What is the melting point of butane in degrees Celsius?

The melting point of butane is indeed around -138 degrees Celsius. This temperature is significant because it represents the point at which butane transitions from a solid to a liquid state. Understanding the melting point is crucial for plumbing contractors when dealing with the storage and handling of liquefied gases, as it affects the conditions under which these materials can be safely used in various applications. The melting point also provides insights into the characteristics of butane as a fuel and refrigerant, indicating its usability across different temperatures. Knowledge of such properties is essential for ensuring proper safety measures and effective system design when working with butane and similar substances in plumbing systems.
