By using the ideal gas equation, we get
⇒ 
or,
⇒ 
By substituting the values, we get
Answer:
32.4 K
Explanation:
Initial pressure P1= 50.0mmHg
Initial temperature T1= 540K
Final temperature T2=????
Final pressure P2= 3 mmHg
From
P1/T1= P2/T2
P1T2= P2T1
T2= P2T1/P1
T2= 3×540/50.0= 1620/50.0
T2= 32.4 K
The answer is that they havent reached their full form yet.
