Does propane liquid escaping from a container rapidly drop in temperature?

Does propane liquid escaping from a container rapidly drop in temperature?

• A. True
• B. False
• C. Dependent on environment
• D. Only in winter

Answer: (A)

When liquid propane escapes from a container, it undergoes a rapid phase change from liquid to gas. This process absorbs heat from the surrounding environment, resulting in a significant drop in temperature. As propane vaporizes, it requires energy to break the bonds between liquid molecules; this energy comes from the heat of the container and the air around it. Consequently, the temperature of the liquid propane decreases significantly during this phase change, leading to a very cold gas being released. The other choices suggest varying conditions or scenarios that do not affect the fundamental principle of propane's behavior when escaping from a container. Whether it's winter or summer, or the environment is considered, the gas's property of absorbing heat during vaporization remains consistent. Therefore, the statement that propane liquid escaping from a container rapidly drops in temperature is true.
