1
platinum-iridium block preserved at the Bureau of weights and Measures.
Mass.
2
an expression sometimes employed to indicate the mass of 1 mL (not cc, which is very slightly different) of a standard substance, such as water, at a specified temperature, relative to water at 4°C taken as unity.
Relative density.
3
the fundamental unit on which are based all metric standards and measurements of length and area and of volumes derived from linear measurements
Meter.
4
Arise from random fluctuations in the temperature or other external factors and from the variations involved in reading instruments. It can be corrected by careful analysis and refinement of techniques
Variable determinate errors.
5
assigned a unit known as the degree.
Temperature.
6
Defined as force per unit area; the unit commonly used in science is dyne/cm.
Pressure.
7
The ratio of the mass of an object, determined in or referred to a vacuum, at a specified temperature, to the volume of the object at the same temperature.
Absolute density.
8
differs from absolute density only in that the mass of the object is determined in air;
Apparent density.
9
Atmosphere is measured using?
Barometer.
10
The results of a series of tests will yield a random pattern around an average or central value, known as the mean
Indeterminate.
11
The standard of mass is the kilogram.
Mass.
12
What is the standard for gas law?
Kelvin.
13
Zero degree on the centigrade scale equals 273.15 on the Kelvin Scale.
Temperature.
14
A push or pull required to set a body in motion.
Force.
15
The fundamental unit of the metric system
Meter.
16
more useful in comparing variability.
Coefficient of variation percent.
17
Errors that although sometimes unsuspected, may be avoided or determined and corrected once they are uncovered
Determinate.
18
If the object and masses are made of the same material, or have the same density, there will be no difference in the buoyant effect, and the apparent density will be identical with the absolute density. (True/False)
True.
19
What is the equipment use to measure length?
Vernier caliper.
20
the average deviation from the mean
Standard deviation.
21
Vapor pressure is measured using?
Manometer.
22
What are the three fundamental dimensions
Length, Mass, Time.
23
The measurable quantity, is also derived from length.
Volume.
24
The larger the mass of the body and the greater the required acceleration, the greater the force that one must exert.
Mass.
25
The agreement between the data and the true value
Accuracy.
26
classified as kinetic energy or potential energy.
Work and energy.
27
Mass in grams /Volume in millimeter
Absolute density.
28
the lowest and highest value
Range.
29
A measure of the agreement among the values in a group of data
Precision.
30
What are the three types of density
Apparent density, Absolute density, Relative density.
31
may be defined as the ratio of the mass of a substance to the mass of an equal volume of another substance taken as the standard.
Specific gravity.
32
frequently defined as the condition of a body that gives it the capacity to do work.
Work and energy.
33
Pressure is often given in atmospheres (atm) or in centimeters or millimeters of mercury.
Pressure.
34
For specific gravity of liquid containing Mercury or lead to make it buoyant.
Hydrometer.
