Explanation:
Hello there!
In this case, since this is a problem in which the pressure of the gas remains constant, we can use the Charles' law as a directly proportional relationship between temperature (in Kelvins) and volume given by:

Thus, solving for the final volume as the temperature is decreased to -80.00 °C, we obtain:
