33.解析:(1)分子间距离增大时,分子间引力和斥力都减小,但斥力减小得快,故A错误;布朗运动反映了液体分子在永不停息地做无规则热运动,故B错误;伞面上有许多细小的孔,却能遮雨,是因为水的表面张力作用,故C正确;由理想气体状态方程=C可知,压强不变,体积增大,温度升高,那么它一定从外界吸热,故D正确由理想气体状态方程=C可知,体积不变,当温度降低,压强减小,分子每秒平均碰撞次数减小,故E正确(2)对于左侧气体,初状态:p1=20cmHg,l1=24cm,240K末状态:l1=1 △h=25cm根据理想气体状态方程矛4S_p1'S一对于右侧气体,初状态:p2=p1-Pg(l1-l2)=12cmHgl2=16cm,T=240K末状态:p2=1-pg(l1-2),l2=2-△h=15cm根据理想气体状态方程有2P2'L2s联立可得T=375K答案:(1)CDE(2)375K
