解析 C。“Beaker”是烧杯;“Test tube”是试管;“Graduated cylinder”是量筒,用于测量液体体积;“Flask”是烧瓶。正确答案是 C,因为只有量筒是专门用来测量液体体积的。涉及的词汇有 beaker、test tube、graduated cylinder、flask,语法上本题是简单的特殊疑问句,考查对实验仪器名称的理解。
试题来源: 解析 C。选项 A“Test tube”是试管,主要用于少量物质的反应等,不能测量液体体积。选项 B“Beaker”是烧杯,通常用于盛装液体等,也不能准确测量体积。选项 C“Graduated cylinder”是量筒,可以用来测量液体体积。选项 D“Flask”是烧瓶,用于反应等,不是测量体积的仪器。

What Instrument Is Used to Measure Electric Current An instrument that can measure the electric current is called an ammeter. The ammeter must connect in series with the circuit whose current is to be measured. Other various instruments are also used to measure the electric current. Hall effect ...
What SI units are used to measure power? Work and Power: When force acts on an object to causes a displacement, it is said thatworkhas been done upon that object. It is crucial to note that the force must be the cause of the displacement in order to consider work done. ...
