我想問下如果有個substance既melting point係-10。c而boiling point就係123。c.
咁個個substance係solid,liquid定係gas form 係room temperture呀?解釋唔該!
有中英解釋^^

✔ 最佳答案
如果個subtance既melting point係-10℃咁姐係個substance會係-10℃個陣變solid
而boiling point係123℃就係話個substance會係123℃個陣變gas
所以room temperature個陣應該會係liquid.
Since the melting point of the substance is -10℃,
it means the substance will become solid when its temperature reaches -10℃.
On the other hand, the boiling point of the substance is 123℃,
it means the substance will become gas when its temperature reaches 123℃.
So the substance should be liquid when it is in room temperature

咁梗係LIQUID 啦,
MELTING POINT= 溶點, 由SOILD 變LIQUID, 家下係-10度
BOILING POINT = 沸點, 由LIQUID 變GAS, 家下係123度
ROOM TEMPERTER 係25.5 度.
MP< BP, 所以係LIQUID. 如果你都係唔明, 用" 水" 黎想像下啦.
