Interpretation:
Conditions required for a liquid to boil are to be determined.
Concept Introduction :
Particles are less closely packed in liquids than they are in solids. When kept in a container, liquids adopt that shape. Compression is challenging in liquids because there is less room for particle mobility. Liquids' forms are not fixed in volume while having a fixed volume.
Answer to Problem 13LC
Liquid boil when the vapor pressure of the liquid becomes equal to atmospheric pressure.
Explanation of Solution
The average kinetic energy of a liquid's particles rises as it warms. As more and more molecules can reach the liquid's surface and enter the vapor phase, the rate of evaporation accelerates. The liquid eventually reaches a point where all the molecules have enough kinetic energy to evaporate. Appropriate temperature and pressure are both required for a liquid to boil.
When the vapor pressure and atmospheric pressure are equal, boiling will happen. It is referred to as the boiling point. The liquid molecules will be able to spread out and transform into gas without any external pressure.
