增大。33.(1)ADE【解析】图中b所对应位置处分子力为零,此时r=7,当r ro时分子力表现为引力,分子B从b所对应位置开始经过c、d所对应位置运动的过程中,分子力做负功分子势能增加,所以在b所对应位置处分子B的势能最小,A项正确,B项错误;分子B由b所对应位置运动到c所对应位置的过程中分子力做负功,做减速运动,C项错误;分子B由c所对应位置运动到d所对应位置的过程中,分子力逐渐减小,加速度也逐渐减小,D项正确;若分子B从a所对应位置以速度vo释放,由a所对应位置运动到b所对应位置过程中分子斥力做正功,而两次运动过程由b所对应位置到d所对应位置,分子力做的负功相同故从a所对应位置达到d所对应位置时的速度会更大,E项正确。(2)【解析】(|)选储水罐内的气体为研究对象,有初状态:1=120kPa,V1=3L(1分)打入气体的压强p2=100kPa末状态:p3=240kPa,V3=V1=3L(1分)等温变化,由玻意耳定律得力V1 p2V2=p3V3(1分)解得V2=3.6L(2分)()选打完气后储水罐内的气体为研究对象,有初状态:p3=240kPa,T1=300K(1分)末状态:T2=280K(1分)假设储水罐不漏气,体积不变,由查理定律得(1分)解得p4=224kPa>175kPa,故漏气(2分)
