Our general chem 2 class is at it again with another cool demo with glow sticks! They looked at the reaction of the glow stick in different temperatures of water: ice cold water, room temp water, and hot water. The brightest glow stick is in the hot water beaker. Why do you think that is? Comment below ⬇️ #frostburgstateuniversity #college #stemeducation #chemistry | Frostburg State University Chemistry and Physics

لماذا يغلي الماء عندما ينخفض الضغط؟ الغليان يحدث عندما يصبح ضغط بخار الماء مساويًا للضغط الخارجي المحيط به. عند الضغط الجوي الطبيعي (1 atm)، يغلي الماء عند 100°C. لكن عندما نقلل الضغط: يقل الضغط الخارجي فوق سطح الماء. يصبح من السهل على جزيئات الماء أن تتحرر وتتحول إلى بخار. بالتالي تنخفض درجة غليان الماء. لذلك، عند ضغط منخفض جداً (كما يحدث داخل غرفة التفريغ)، قد تنخفض درجة الغليان إلى 25°C أو أقل. وهذه تقريباً درجة حرارة الغرفة، فيبدأ الماء بالغليان بدون أي تسخين.
