1000 m3 of pure water has a mass of what? - correct answer-1 liter (1000m3) of pure water
at standard temperature and pressure has 1 kilogram of mass.

By what factor do metric prefixes use? - correct answer-Factor of 10

Control group - correct answer-The control group is defined as the group in an experiment or
study that does not receive treatment by the researchers and is then used as a benchmark
to measure how the other tested subjects do. The situation used as the basis of comparison
