✔ 最佳答案
在氣壓低的情況下,水的沸點會低於攝氏100度原因是,氣壓低可理解作少空氣
在少空氣的情況下,水比較有機會由液體變為氣體,即沸點會較低
例子,在高山上的氣壓會較低,
所以在高山上用水煮公仔面吃,有機會肚痛

2 reasons:
1. If the air pressure is less than sea level, such as on top of a mountain say 500m high, boiling point is lower.
2. impurities in water. If a small amount of alcohol is present, boiling point of the mixture is lower.
