[单选题]
Which row represents the enthac2q3a zp .lf*8i-0rq rxc rh.glpy change for condensatitk tsod5t q3+*fk;s+r on and sublimation phase changf r 3s++*tktq do5;kstes?
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 to5+pn: n xjrslb p,28ohwz)8j 6rkne0r liquid) requires making bonds and therefore, releases energy. Sublimation (solid to gas) requires breaking bonds and therefore ab: k)rr ,8plnprz2ns0n+bexo 8j6w 5hjsorbs energy.
