问题:

图1是同学们在探究液体内部压强情况的六幅图,除②图杯中装的盐水外,其余杯里装的都是水。请你仔细观察这六幅图后回答:

(1)实验前要正确安装压强计并检查压强计的气密性。若压强计的气密性很差,用手指不论轻压还是重压橡皮膜时,发现U形管两边液柱的高度差变化              (选填“大"或“小")。把调节好的压强计放在空气中时,U形管两边的液面应该                 。

(2)比较①②两幅图,可以得出:液体内部压强大小跟液体的              有关;

(3)比较⑤⑥两幅图,可以得出:液体内部压强大小还跟液体的            有关;

(4)比较③④⑤三幅图,可以得出:                            

(5)某同学认为影响水的内部压强大小的因素不是水的深度(即图中的h值)而是离水底的距离(即图中的d值),且d越大,压强越小。根据所学,你是否认为水内部压强大小跟水底的距离d有关?           (选填“有关”“无关”或“不确定”)。
