如图所示，一生一熟两个鸡蛋，一起放入装有水的烧杯中，往水中边加盐边搅拌，观察到原来都沉底的鸡蛋有一个先浮出液面。

（1）为了探究先浮出液面的是生鸡蛋还是熟鸡蛋，小东先用电子秤称出一个生鸡蛋的质量为        g（如图），将这一鸡蛋煮熟冷却后再称出其质量为56.40g。通过测量还发现鸡蛋煮熟后体积几乎不变，说明鸡蛋煮熟后的平均密度        （填“变大”、“变小”或“不变”）。由此可判断：先浮出液面的是        鸡蛋，此鸡蛋未露出液面的上浮过程中，受到的浮力          （填“大于”、“小于”或“等于”）重力。

（2）图中，从烧杯侧面观察水中的鸡蛋，所看到的是鸡蛋正立的（    ）

A．放大的虚像

B．放大的实像

C．等大的虚像

D．等大的实像（3）为测出鸡蛋的体积，小东进行如下操作：

①用电子秤称出空烧杯的质量m₁；

②将溢水杯装满水，把鸡蛋轻轻放入溢水杯中并用烧杯接住溢出的水；

③用电子秤称出烧杯和溢出的水的总质量m₂。

则鸡蛋体积的表达式V＝                   （水的密度用ρ_水表示）。
