Answer:
C. Reducing the air pressure allows the molecules to escape.
Explanation:
Lower air pressure can be found in the mountain or any high ground place. In this place, you will need less temperature to boil water or other liquid.
A liquid phase will change into gas when it reaches the vapor pressure of the surrounding air. At that point, the molecule can move freely as the gas phase. Since the atmospheric pressure is preventing the liquid to become gas, if the pressure is lower, the liquid can boil at a lower temperatures.
Answer:
A sample of helium gas in a balloon is compressed from 4.0 L to 2.5 L at a constant temperature. If the pressure of the gas in the 4.0-L volume is 210 kPa, what will the pressure be at 2.5 L? P2 = 340 kPa (336 rounded to 2 s.f.)

If we burn all of the remaining fossil fuels on Earth, almost all of the ice in Antarctica will melt, potentially causing sea levels to rise by as much as 200 feet, which will b enough to drown and flood most of the major cities in the world.
Answer: I think it’s heating the particles in the ethanol caused them to react and bond with gases in the air which carried the liquid ethanol particles around the room
