boiling point trivia questions
The boiling point is the temperature at which a liquid changes into what?
Answer: Gas
Bonus fact: Boiling occurs throughout the liquid.
How does lower atmospheric pressure affect water's boiling point?
Answer: It lowers it
Bonus fact: At high altitude, water boils below 100°C.
Does evaporation occur only at a liquid's boiling point?
Answer: No

What process separates crude oil into fractions by boiling point?
Answer: Fractional distillation
Bonus fact: A distillation column separates hydrocarbons.
What happens to water's boiling point at higher altitude?
Answer: It decreases
Bonus fact: Lower air pressure lets water boil at a lower temperature.
What type of distillation uses a fractionating column to separate liquids with closer boiling points?
Answer: Fractional distillation
Bonus fact: Repeated vaporization and condensation improve separation.
Why does liquid nitrogen boil rapidly at room temperature?
Answer: Its boiling point is far below room temperature
