本题目来源于试卷: What Drives Chemical Reactions D.1 Measuring Enthalpy Changes，类别为 IB化学
[单选题]
Which row represents the entl m3 f-bg5m5f0mvlz4,o wxkj1halpy change for condensation and sublimati;i,6ptg u(+ c6s2oqywvi hhf8on phase cha;wv66qyfu2 8 ict+ ip(ghhso,nges?
A. Condensation is endothermic ;Sublimation is exothermic
B. Condensation is endothermic ;Sublimation is endothermic
C. Condensation is exothermic ;Sublimation is exothermic
D. Condensation is exothermic ;Sublimation is endothermic
参考答案: D
本题详细解析:
Condensation (gas to liquid) requires maki6a f;-ehdslbvp8 /0 reng bonds and therefore, releases energy. Sublimatiodrefp ba6;8elvh/ s-0n (solid to gas) requires breaking bonds and therefore absorbs energy.
