<span> (a) the work done on the gas
From the definition of work in thermodynamics,
W = integral (PdV)
It is said that the process above is done at constant volume. Therefore, the value of dV is zero which would result to
</span>W = integral (PdV) = 0
<span>
(b) the increase in internal energy of the gas
</span> From the first law of thermodynamics,
ΔU = Q + W
where U is the change in internal energy, Q is the heat and W is the work which is zero in this case
ΔU = Q = 209 J<span>
(c) its final temperature
at constant volume,
Q = nCv(T2 - T1)
209 = 1 (3R/2) (T2 - 300)
T = 316.76 K</span>
Answer: The potential energy of both toy vehicles (purple and pink) decreased. Since the pink toy was moved closer to the magnet, it will have less potential energy because of the short distance it will take to travel to the magnet.

-- "Weight" is the gravitational attraction between TWO objects.
-- Its 'strength' depends on the mass of BOTH masses.
If either mass changes, then the gravitational force between them changes.
-- Your 'weight' on Earth depends on your mass and the Earth's mass.
-- Your 'weight on the moon depends on your mass and the Moon's mass.
From the list of choices, the best one is "The Earth and moon have
different values for the acceleration due to gravity.", although that
doesn't really explain much.
