Answer:
Replication
Explanation:
<em>The process of running multiple trials for each measurement during an experiment and finding the average is referred to as </em><em>replication.</em>
Replication is one of the attributes of good measurements/experiments because it reduces variability and increases the accuracy of the outcome. It also ensures that relevant statistical analysis can be carried out on the data collected via replicative measurements.

Answer:
100,000 times
Explanation:
Luminosity is the measure of brightness of a star. It is measured by examining the radiant energy emitted by the stars per second. Rigel's radius is about 80 times that of the Sun's radius. Therefore, its luminosity is about 100,000 times the sun’s luminosity.

Answer:
The answer to your question is 720.5°K
Explanation:
Data
Volume 1 = 285 ml
Temperature 1 = 355 °K
Pressure 1 = 1.88 atm
Volume 2 = 435 ml
Temperature 2 = ?
Pressure 2 = 2.5 atm
Formula
To solve this problem use the combined gas law
P1V1 / T1 = P2V2 / T2
- Solve for T2
T2 = T1P2V2 / P1V1
- Substitution
T2 = (355)(2.5)(435) / (1.88)(285)
- Simplification
T2 = 386062.5 / 535.8
- Result
T2 = 720.53°K
Conclusion
The gas must be heated to 720.5°K
