Answer:

Explanation:
We are given that 







We have to find the exit temperature.
By steady energy flow equation 



Substitute the values 




 
        
             
        
        
        
The final volume of the gas is 238.9 mL
Explanation:
We can solve this problem by using Charle's law, which states that for a gas kept at constant pressure, the volume of the gas (V) is proportional to its absolute temperature (T):

Which can be also re-written as

where
 are the initial and final volumes of the gas
 are the initial and final volumes of the gas
 are the initial and final temperature of the gas
 are the initial and final temperature of the gas
For the gas in the balloon in this problem, we have:
 is the initial volume
 is the initial volume
 is the initial absolute temperature
 is the initial absolute temperature
 is the final volume
 is the final volume
 is the final temperature
 is the final temperature
