ACT NO. 3: Measuring Solids Flashcards
Perhaps one of the most fundamental concepts in science.
Measurements
Measurement is a technique in which the properties of an object are determined by comparing them to a ________.
standard
A highly precise laboratory balance for measuring mass.
Analytical Balance
Used for exact weighing applications of small amounts of material.
Analytical Balance
Designed with an enclosed measuring pan.
Analytical Balance
In analytical balance, always record weighing to the nearest ________.
0.0001 g
Essential in setting the properties of an object, it is useful for determining identity and purity by comparing values to a standard.
Measurement
The word “measurement” comes from the Greek word “_______,” which means “__________________.”
metron, limited proportion
The metric system was developed in 1790, revised, and renamed as Sl system (_____________________________). This is used in almost all countries except for the United States.

Are smaller in size and are attached to the upper portion of the vernier caliper.
Upper jaws
The most prominent feature of a vernier caliper. This is designed to grip objects firmly between them for measurement.
Lower jaws
The large scale which runs along the body of the vernier caliper.
Main scale
A smaller scale attached to the main scale and can move along the main scale as the jaws are opened or closed.
Vernier scale
Used to measure the depths of holes.
Depth rod
