To determine which law is appropriate for solving the problem, we need to consider the variables involved: volume, temperature, and pressure. Charles' Law relates volume and temperature at constant pressure, but in this problem, both temperature and pressure are changing. Therefore, Charles' Law is not suitable.The Combined Gas Law, on the other hand, relates pressure, volume, and temperature, making it applicable when all three variables change. The formula for the Combined Gas Law is:
where:-
and
are the initial and final pressures,-
and
are the initial and final volumes,-
and
are the initial and final temperatures in Kelvin.Given that both temperature and pressure change in this problem, the appropriate law to use is the Combined Gas Law.
