Answer with Complete Solution 100% Correct |
New 2026 | Graded A+
What is Chemistry? - ANSWERS Is the science that seeks to understand what
matter does by studying what atoms and molecules do
(so its the study of matter, atoms, and molecules and how they interact with each
other)
What are the steps of the scientific method? - ANSWERS 1) Observation
2) Hypothesis
3) Experiment
4) Laws
5) Theories
Define each part of the scientific method - ANSWERS 1) Observation: involves
measuring or observing some aspect of nature
2) Hypothesis: is a tentative (uncertain) interpretation of the observation (aka an
educated guess)
> if hypothesis are not confirmed, they are revised & tested through further
experimentation
3) Experiment
, 4) Laws: summary of the results of many observations (so its a formal explanation
of what you confirm)
5) Theories: are models that explain & give the underlying causes for observations
& laws ( so its a more formal universal model)
Explain how the scientific method would be used in a hospital setting
? - ANSWERS 1) Observation would be like observing the signs & symptoms of
the patient
2) Hypothesis would be like making an educated guess that the patient has a cold
or covid-19
3) Experiment would be like measuring the patients temperature, oxygen levels
etc.
4) Law or conclusion would be like making a conclusion and having a diagnose of
the patients case
What are the metric conversions for length? - ANSWERS 1 kilometer = 1000
meters
1 meter = 100 centimeters
1 cm = 10 millimeters
2.54 cm = 1 inch
1 meter = 39.37 inches
