1. Precision - Correctness of a measurement

2. Mili - 1/1000

3. Graduated cylinder - Instrument to measure volume

4. +- Value - Uncertainty value of measurement

5. Centi - 1/100

6. Kilo - 1000

7. Accuracy - Degree of exactness of a measurement

8. Balance - Instrument to measure mass

Answer is:

1. precision - degree of exactness of a measurement.

Precision is a description of random errors, a measure of statistical variability.

2. milli - 1/1000.

For example, millimeter (abbreviated: mm, a thousandth part of metar) is an unit of distance in the metric system.

3. graduated cylinder - instrument to measure volume.

Cylinder use cubic millimeter (symbol: mm³) volume measurement unit (takes up space).

4. +- value - uncertainty value of measurement.

5. centi - 1/100.

For example, 1 cg = 0.01 g ; one centigram is equal to 10⁻² grams.

6. kilo - 1000.

For example, kilogram (symbol: kg) is the base unit of mass in the International System of Units. 1 kg = 1000 g.

7. accuracy - correctness of a measurement.

Accuracy is the closeness of a measurement to the true value.

8. balance - instrument to measure mass.

Balance is an instrument for comparing the mass of two bodies.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
