Final answer:
Propane liquid escaping from a container rapidly drops in temperature.
Step-by-step explanation:
The statement (T/F) Propane liquid escaping from a container rapidly drops in temperature is true. When a volatile liquid like propane escapes from a container, it undergoes a phase change from liquid to gas. This phase change requires energy, which is taken from the surroundings, leading to a decrease in temperature. Therefore, when propane liquid escapes rapidly, its temperature drops.
For example, when a propane tank is used for a barbecue grill, if the valve is open and the propane gas escapes rapidly, the tank and the immediate surroundings will cool down due to the temperature drop caused by propane evaporating.
