The volume of a liquid is often measured in ___. A. cubic meters B. liters C. grams D. newtons 相关知识点: 试题来源: 解析 B。解析:液体体积通常用升来测量。A 选项立方米通常用于较大体积物体;C 选项克是质量单位;D 选项牛顿是力的单位。
A. 25ml B. 25 mls C. 25 milliliter D. 25 milliliters long 相关知识点: 试题来源: 解析 A。体积的正确记录方式是数字加上单位缩写,milliliter 的缩写是 ml,所以选 A。B 选项 mls 错误;C 选项 milliliter 没有用复数形式且不是正确的记录方式;D 选项太啰嗦不是标准的数据记录方式。反馈...
The planned volume of a liquid in an experiment is 60ml, but the measured volume is 57ml. Find the percentage error. A. 5% B. 6% C. 7% D. 8% 相关知识点: 试题来源: 解析 A。百分比误差 = (|60 - 57| / 60)× 100% = (3 / 60)× 100% = 5% ...
Specific gravity(SG)is the ratio of the mass of a product when measured against the mass of an equal volume of water. Because specific gravity is expressed as a ratio, it has no measurement units. However, the SG can vary according to the temperature of the product. It is quite common ...
Improvement to the measured volume of liquidTRIBOUT ADRIEN-MARCEL-LUCIEN
It is not possible to measure the volume directly, and unfortunately there is no such device as a volume sensor, however if you know the dimensions of the space filled with liquid, you can easily determine the volume. You can measure the height of a liquid using a level sensor, which can...
How would one read the volume of the liquid in the graduated cylinder to the proper number of significant figures?If a graduated cylinder has calibrations of one-tenth ml and a liquid is measured between 1 to 9 degrees Celsius, how many significant figures ...
[translate] aThe liquid level in the constant-level tank was measured using a movable bar of discrete level gages accurate to 2 mm. 液体水平在恒定级坦克使用分离水准仪一个可移动的酒吧被测量了准确到2毫米。[translate]
The density of a liquid is far easier to measure than that of a solid or gas. The volume of a solid can be difficult to obtain, while the mass of a gas can rarely be measured directly. You can, however, measure the volume and mass of a liquid directly an
The relevance of bioassays is associated with the fact that an integrated response to a complex mixture can be obtained, which can contain more substances than the measured ones. Thus, we may conclude that WFD are insufficient to draw conclusions about water quality, and the growth inhibition of...
