我覺得睇個 (三角形)H＞0 《吸熱》同 (三角形)H＜0 《放熱》
好難分...可唔可以解釋一下點了少果邊指向0係吸熱
指向H係放熱呀?
分辨放熱和吸熱問題

✔ 最佳答案
ΔH means the change of heat.If ΔH > 0, that means there is heat gain of the substance, so the reaction is endothermic
(吸熱).
If ΔH < 0, that means there is heat loss of the substance, so the reaction is exothermic
(放熱).
