Answer:
The volume increases by 100%.
Explanation:
<u>Step 1:</u> Data given
Number of moles ideal gas = 1 mol
Initial temperature = 305 K
Final temperature = 32°C + 273.15 = 305.15 K
Initial pressure = 2 atm
final pressure = 101 kPa = 0.996792 atm
R = gasconstant = doesn't change
V1 = initial volume
V2= the final volume
<u>Step 2: </u>Calculate volume of original gas
P*V = n*R*T
(P*V)/ T = constante
(P1 * V1) / T1 = (P2 * V2)/ T2
In this situation we have:
(2atm * V1)/ 305 = (0.996792 *V2) / 305.15
0.006557*V1 = 0.003266*V2
V2 = 2*V1
We see that the final volume is twice the initial volume. So the volume gets doubled. The volume increases by 100%.

The answer is C.) Placing Wind Barriers
The reasoning is because irrigation, if used too much, causes water erosion. Planting crops deeper in the ground would would prevent the plants from being uprooted. Finally, terracing would prevent from run-off eroding the ground away from the plants.
This is because red tinted lights are easier on your eye. If you want to see the stars your eyes first need to get used to the darkness. Since the sodium in a lamp gives an orange-ish tint this is better for your eyes.
Another reason could be that sodium lights are less bright and don't pollute the sky with as much light which also makes it better for seeing stars.
You can look up pictures of the streets lights to see the color difference.
