[单选题]
Which row represents the fit wi8xxu ;62y1nxb( enthalpy change for condensation and sublimation phl n2zo56h )drlase changes5 or6z)ld2l hn?
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 making bonds and tc7u( n,h5/rrcj esi:cherefore, releases energy. Sublimation (solid u/eichr jr nc5,s:(c7to gas) requires breaking bonds and therefore absorbs energy.
