What happens to the volume of propane liquid when it is released into the atmosphere?

  1. It decreases drastically

  2. It remains the same

  3. It expands into vapor

  4. It solidifies

The correct answer is: It expands into vapor

When propane liquid is released into the atmosphere, it undergoes a phase change from liquid to gas, leading to a significant expansion in volume. This occurs because propane, when in its liquid form, occupies a much smaller volume compared to its gaseous state. As it is exposed to the lower pressure of the atmosphere, propane evaporates and expands into vapor, which takes up much more space. This behavior is a fundamental characteristic of volatile liquids, such as propane, and is influenced by the principles of thermodynamics and the properties of gases. The transformation from liquid to gas is not only rapid but also results in a dramatic increase in the volume of the substance.
