用水管隔空吸引鋁罐?│《科科學會了》把課本的「靜電(摩擦起電)」變有趣!-資源代表圖
靜電是什麼?靜電指的是電荷在物體表面不平衡分佈所引起的現象,當兩個物體互相摩擦時,電子會從一個物體轉移到另一個物體上,這種因為電子轉移而產生的電荷現象,就稱為靜電。靜電不會像電流一樣流動,它是暫時停留在物體表面的電荷,直到遇到導體或接地後才會釋放。以日常生活中的例子來說,當我們用塑膠梳子梳頭髮時,會發現頭髮變得容易吸在臉上,這是因為梳頭的過程中,電子從頭髮轉移到梳子上,使頭髮和梳子帶靜電,與臉產生吸附現象。

【自然系列-化學 | 化學反應02】(化學平衡)化學反應的神奇比例-下集-資源代表圖
古德柏格和瓦格兩位哥倆好,因為貝特羅的實驗開始反覆猜想與驗證所有可逆反應在溫度不變的情況下,反應到最後,原料跟產物會呈現特殊的比例。而這些固定比例則源自於物質的濃度和吸引力所達到的「反應平衡」。

功率是被瓦特定義的?蒸汽機和馬怎麼比較作功大小?(功率的起源)│功與功率│科學家的故事-瓦特│LIS情境科學教材-資源代表圖
功率最早是為了要比較馬和蒸汽機的工作效率,才有了這個定義。當初瓦特雖然改良了蒸汽機,但他卻不知道該怎麼證明蒸汽機比馬更有效率,因此他開始思考功以及功率的概念。後來他也創造了馬力作為功率的單位。瓦特的成就,也讓他的名字成為現在公制的功率單位。
