At what point will liquid alcohol change to vapor?
Boiling
Melting
Fusing
Freezing
The boiling point is the point above which the liquid state does not exist. Evaporation can occur from the liquid state at lower temperatures as well, but there will be no "boiling" (rapid formation of vapor bubbles) until the boiling point is reached.
The answer to the question is "boiling". Liquid alcohol will change to vapor at the boiling point. The boiling point is the temperature at which the vapor pressure of the liquid alcohol is equal to the atmospheric pressure. At this temperature, the liquid alcohol undergoes a phase transition and turns into vapor.
To determine the boiling point of alcohol, you can use various methods:
1. Look up the boiling point in a reference source: You can check a chemistry textbook, encyclopedia, or an online database to find the boiling point of alcohol. Different alcohols have different boiling points, so it's important to specify the particular alcohol you are referring to.
2. Conduct an experiment: You can set up a simple distillation apparatus and perform a boiling point determination experiment. This involves heating the alcohol under controlled conditions and monitoring the temperature at which it starts to boil. This method provides a more accurate and specific boiling point for a given type of alcohol.
Remember that boiling does not always occur at a specific temperature. It depends on the pressure as well. The boiling point of alcohol can change at different atmospheric pressures. Hence, it is important to specify the pressure conditions when discussing the boiling point of alcohol.
