Final answer:
The new pressure inside the canister is approximately 2300 torr. The answer is not provided among options.
Step-by-step explanation:
To find the new pressure inside the canister, we can use the combined gas law equation: P1V1/T1 = P2V2/T2. We know the initial pressure (P1) is unknown, the initial volume (V1) is 8.08 L, the initial temperature (T1) is 79°C + 273.15 = 352.15 K, the final volume (V2) is the same as the initial volume, and the final temperature (T2) is 30°C + 273.15 = 303.15 K.
Let's plug in the values into the equation and solve for P2:
P1 * 8.08 / 352.15 = P2 * 8.08 / 303.15
P2 = P1 * 8.08 * 303.15 / 352.15 / 8.08
P2 = P1 * 303.15 / 352.15
Now we can substitute the known values to find P2:
P2 = 360 * 303.15 / 352.15
P2 ≈ 310.53 kPa
Converting the pressure to torr, we get:
P2 ≈ 310.53 kPa * 7.5 torr / 1 kPa ≈ 2329.925 torr ≈ 2300 torr
Therefore, the new pressure inside the canister is approximately 2300 torr. Answer choice (d) 920 torr is not correct.
Hence, The answer is not provided among options.
