Answer:
The correct option is: a) saturated
Explanation:
Relative humidity is a primary measurement of humidity. At a given temperature, relative humidity describes the present state of absolute humidity relative to the maximum humidity.
It is generally expressed as percentage. Therefore, <u>100% relative humidity means that the air is entirely </u><u>saturated</u><u>.</u>
<u>Answer</u>;
Falsfiable
<h3><u>Explanation</u>;</h3>
- <u>Scientific Hypothesis</u> is a proposed set of phenomena that must be testable with evidence from the natural world. If an hypothesis cant be tested then it's not a scientific hypothesis.
- <u>Scientific Theory</u> is a broad explanation for a wide range of phenomena and usually integrate many individual hypothesis. The theory must be testable with evidence to support the theory.
- <u>Scientific Laws</u> on the other hand is a statement based on repeated experimental observations that describes some aspect of the world.
- <em><u>Scientific statement, hypothesis, or theory should have falsifiability or should be falsifiable. Falsifiability refers to the capacity for some proposition, statement, theory or hypothesis to be proven wrong.</u></em>
Answer:sNo, Air is not an element It's a mixture of a variety of gases.
Explanation:
The chlorine isotope with 18 neutrons has an abundance of 0.7577 and a mass number of 35 amu. To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together.
Answer:
1 x 10^13 stadiums
Explanation:
We are given that;
1 stadium holds = 1 × 10^5 people
Number of iron atoms is 1 × 10^18 atoms
Assuming the stadium would carry an equivalent number of atoms as people.
Then, 1 stadium will carry 1 × 10^5 atoms
Therefore,
To calculate the number of stadiums that can hold 1 × 10^18 atoms we divide the total number of atoms by the number of atoms per stadium. Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18
atoms ÷ 1 × 10^5 atoms/stadium =
1 × 10^13 Stadiums
Thus, 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
