點解solution一定係liquid??

樓上錯, In chemistry, a solution is a homogeneous mixture composed of two or more substances.
gas, liquid, solid都可以做solution

這裏可以幫到你

gas/solid + liquid = solution
solution + crystallization = solid
solution + distillation = liquid
solution + heating = gas

唔係一定,只係以日常實驗與生活中,液體佔大部份

溶液 , 有埋個液字 , 唔係液體係咩

因為只有liquid先可以solution!!

(solution)解作溶液，所以係液體(liquid)，對嗎。
