初二第一次月考冲刺物理第4天
【分析】液体内部存在压强,其特点是:液体对容器底和容器壁都有压强,液体内部向各个方向都有压强,液体内部压强随深度的增加而增大,在同一深度,液体内部向各个方向的压强相等,不同液体内部的压强还与液体的密度有关;故橡皮膜的形状由玻璃管所受的液体压强大小决定,故据此分析即可判断.
【解答】解:A、玻璃管下端更深,所受的液体压强更大,所以应该是下面橡皮膜向上凹得更厉害些,故A错误;
B、玻璃管下端更深,所受的液体压强更大,且下面橡皮膜向上凹得更厉害些,故B正确;
C、玻璃管水平放置在液体中,液体对两侧橡皮膜有向内的压强,所以右侧橡皮膜应该向左凹,故C错误;
D、玻璃管水平放置在液体中,两侧的橡皮膜都应向内凹,故D错误;
故选B.
【点评】本题考查了学生对液体压强公式的掌握和运用,分析时同时考虑影响液体压强的多个因素(如深度、密度).
