在探究液体压强与哪些因素有关的实验中:

(1)如果影响液体的压强的因素有多个,要研究液体的压强与某个因素的关系,需要先控制其他几个因素不变,这在科学探究中被称作______法.

下表是小莉同学用如图所示装置分别测得水和盐水在不同深度时,压强计(U形管中是水)两液注的液面高度情况.

液体深度h

(mm)

压强计
左液面(mm)右液面

(mm)

液面高度差

(mm)

13018621428
26017122958
39015824284
4盐水9015424692
(2)分析表中序号为1、2、3三组数据可得到的结论是:同种液体的压强随深度的增加而______,比较表中序号为3、4两组数据可得到的结论是:不同液体的压强还跟______有关.

(3)为了进一步研究在同一深度,液体向各个方向的压强是否相等,小莉同学应控制的量有______和______,要改变的是______.

(4)小莉同学在学了液体压强公式后,用公式对以上实验的数据进行分析计算,得出金属盒在30mm深处水的压强是______Pa,而从压强计测出的压强为______Pa,由此她发现按液面高度差计算的压强值小于按液体深度计算的压强值,你认为造成的原因是什么?
