Answer:
When gathering data, whether qualitative or quantitative, we can use several tools, such as: surveys, focus groups, interviews, and questionnaires. To help organize data, we can use charts and graphs to help visualize what's going on, such as bar graphs, frequency charts, picture graphs, and line graphs.
If your hypothesis is supported, you might think of ways to refine your hypothesis and test those. Either way, the process of experimentation often leads to whole new questions to explore. The possibilities are infinite, and the search for knowledge is never-ending.
The scientific method is a process that helps answer questions based on observations, carefully planned experiments and deductive reasoning. All scientific inquiry begins with the identification of a problem or question to be answered based on observation.
If the initial hypothesis is not supported, you can go back to the drawing board and hypothesize a new answer to the question and a new way to test it. ... Either way, the process of experimentation often leads to whole new questions to explore. The possibilities are infinite, and the search for knowledge is never-ending.

Explanation:
<u>Answer;</u>
-Work
If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, <u>work </u> is being done.
<u>Explanation;</u>
- Work refers to the application of a given force over a distance. Thus, we can say work is the product of force and distance.
- Energy on the other hand is the ability of a body to change, its location, shape, or state of another body.
- According to the work-Energy principle, a change in the kinetic energy, which is the energy possessed by a body in motion, is equivalent to the net work done on the body.
Part 1 (non-ideal behavior ):
we will use Van der Waals formula:
P = (nRT/(V-nb)) - (n^2 a/V2)
when n (moles of H2) = 18 g / 2 = 9 moles
R (constant) = 0.0821
T(tempreature in kelvin = 20 +273 = 293 K
V(Volume) = 1 L
a (constant for H2) = 0.2476
b(constant for H2) = 0.02661
So by substitution:
∴P = (9*0.0821*293/(1-(9*0.02661))) - (9^2*0.2476/1)
∴P ≈264.6 atm
Part 2 (ideal behavior):
we will use the ideal gas formula :
PV = nRT
when we have n = 9
R= 0.0821
T=293 K
V= 1 L
∴P = (9*0.0821*293)/1 L
∴P = 216.5 atm
