Answer:
-116.42°C
Explanation:
According to pressure law which states that the pressure of a fixed mass of a gas is directly proportional to its absolute temperature at constant volume.
Therefore;
P1/T1 = P2/T2
P1 = 811 mmHg
P2 = 415 mmHg
T1 = 33°C + 273°C = 306 K
Therefore;
T2 = P2T1/P1
= (415 × 306)/ 811
= 156.58 K
Therefore; temperature = 156.58 - 273 = -116.42°C
