34.同学们在实验室里测某种小矿石的密度,选用天平、量筒、小矿石、细线、烧杯和水,进行了如下的实验操作:
A.将小矿石用细线系好后慢慢地放入量筒中并记下总的体积
B.把游码放在标尺的零刻度线处,调节横梁上的螺母,使横梁平衡
C.把天平放在水平桌面上
D.将小矿石放在左盘中,在右盘中增减砝码并移动游码直至横梁平衡
E.在量筒中倒入适量的水并记下水的体积
⑴正确的实验操作顺序是 (只填字母序号);
⑵在调节天平时,发现指针位置如图
甲所示,此时应将平衡螺母向
调(选填“左”或“右”);
⑶用调节好的天平称小矿石的质量。
天平平衡时,放在右盘中的砝码和游码的位置如图乙所示;量筒量出小矿石的体积如图丙所示,由此可知,小矿石的密度ρ= kg/m3;
⑷实验中,由于小英同学不小心把量筒打碎了,但实验室里已没有量筒了,老师就给她增加了一个溢水杯。现请你帮她想办法测出小矿石的体积,写出简要的实验步骤。
