昨天的天氣相較於前幾天 冷了非常多
於是跟我另外兩個室友 三個人都不約而同的想煮泡麵當午餐吃
整件事情就發生在 把水放到鍋子裡 開火下去煮時...
我看到室友的鍋蓋在旁邊 隨手就幫他把鍋蓋蓋上
室友a稱他叫洋蔥 室友b就叫他阿胖好了
洋蔥：不要蓋! 這樣會比較慢滾
我：這樣會比較快吧? 怎麼會比較慢?
洋蔥：你蓋上蓋子 他水蒸發的時候 鍋內壓力上升
沸點就會上升 那自然就會比較慢滾拉
我：你當做你是用壓力鍋在煮泡麵喔
人家壓力鍋是整個密封的
這種只是煮湯用的鍋子 你當它壓力還會上升喔
洋蔥：怎麼不會 你沒唸過高中化學喔 三相圖看過沒有
我：但是你那種爛鍋子 那有可能讓它壓力上升
蓋蓋子是為了讓蒸發的水蒸汽留住 讓熱能不會跑掉吧
阿胖：對呀 蓋蓋子 是為了增加它的對流呀
..........
......................
以上是三個唸物理系的爭吵.......
這個問題吵了好一陣子.......
洋蔥現在還覺得 蓋上蓋子會比較慢滾
而我跟阿胖叫他自己實驗一次 他也不願意
有鄉民 可以跟洋蔥說明一下是誰對誰錯嗎?
