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 thcto -h9b6vf 0q(wcx:f e e- oseni8jd6q/nthalpy change for condensation and sublimation phase changesq6s on j/-ie8d?
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) requtk9wh ii.m 9r(ires making bonds and therefore, releases energy. Sublimation (solid to gas) reqtk(iwir m9h .9uires breaking bonds and therefore absorbs energy.
