✔ 最佳答案

(1) If we add too much solution into the test tube, we can pour some solution back into the reagent bottle. [T] 因為會污染了reagent bottle中的reagent。

(2)The air hole must be closed before lighting up the Bunsen burner. [T]
這是一般的操作程序。

(3)In the laboratory, we usually use mercury thermometers or water thermometers to measure temperature. [F] 沒有 water thermometers 這個東西。

(4) Centimetre is a suitable unit for measuring the height of a building.[F] meter 會較為合適。

(5) One milliltre is equal to one cubic centimetre. [T]

*(6) The weight of an Octopus card can be measured by a triple beam balance. [T] triple beam balance 的準確範圍應該足以秤八達通。
