لماذا تظهر فقاعات عندما تترك الماء في كأس او قنينة لفترة من الزمن؟

Keep going

السبب في ذلك ان الماء يحتوي على هواء مذاب، وعندما تترك الماء جانبا ترتفع

درجة حرارته، وبارتفاع درجة حرارة الماء يصبح أقل قدرة على الاحتفاظ بالغاز،

فكمية الغاز المذاب في الماء تتمدد على درجة حرارته، لذلك يخرج الغاز مكونا

فقاعات.
