Answer:
485 K
Explanation:
Step 1: Given data
- Initial pressure (P₁): 125 atm
- Initial temperature (T₁): 303 K
- Final pressure (P₂): 200 atm
- Final temperature (T₂): ?
Step 2: Calculate the final temperature of the gas
Assuming constant volume and ideal behavior, we can calculate the final temperature of the gas using Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 200 atm × 303 K/125 atm = 485 K
