Answer:
ΔS = - k ln (3)
Explanation:
Using the Boltzmann's expression of entropy, we have;
S = k ln Ω
Where;
S = Entropy
Ω = Multiplicity
From the question, the configuration of the molecules in a gas changes so that the multiplicity is reduced to one-third its previous value. This also causes a change in the entropy of the gas as follows;
ΔS = k ln (ΔΩ)
ΔS = kln(Ω₂) - kln(Ω₁)
ΔS = kln(Ω₂ / Ω₁) -------------(i)
Where;
Ω₂ = Final/Current value of the multiplicity
Ω₁ = Initial/Previous value of the multiplicity
Ω₂ = Ω₁ [since the multiplicity is reduced to one-third of the previous value]
Substitute these values into equation (i) as follows;
ΔS = k ln ( Ω₁ / Ω₁)
ΔS = k ln ()
ΔS = k ln (3⁻¹)
ΔS = - k ln (3)
Therefore, the entropy changes by - k ln (3)
Answer:
A table of motion (for a moving object) usually is something like:
Time I Position:
0s 1m
1s 3m
2s 5m
etc...
Where time is the independent variable and position represents the position of the object at that given time.
We can think in these points as coordinate pairs, for example, we can wrote these 3 pairs as:
(0s, 1m)
(1s, 3m)
(2s, 5m)
Now that we have these points, we can go to a coordinate plane and find these points
(The time would be on the horizontal axis, and position in the vertical axis)
Once you found the points, to complete the graph you need to find a line that connects the points.
An example of this is shown below, where the points used are the ones above, and the line should be straight.
