真係識少少扮代表咋, 我之前睇過講微波加熱既原理, 國際上規定家用微波爐的微波波長為 122 mm, 對應頻率為 2450MHz, 水會係吸收呢個指定範圍既Frequency最好的介質，所以凡含水的物質必定吸收微波, 太高太低都唔得, 所以白光就唔得。 重有微波既能量其實好低, 所以...

is it a F.6 lab?? 2. heat loss to surrounding by conduction, radiation and one that i have forgotton Suggested improvement : use polystyrene cup or vacuum flask instead 3. i am not sure for this anwser thus i can't anwser it
