A gas is placed in a storage tank at a pressure of 36.0 atm at 22.0 oC . As a safety device, a small metal plug in the tank is made of a metal alloy that melts at 180 oC . If the tank is heated, what is the maximum pressure that will be attained in the tank before the plug melts and releases gas?

Respuesta :

Answer : The maximum pressure that attained in the tank will be 55.3 atm

Explanation :

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

[tex]P\propto T[/tex]

or,

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = initial pressure = 36.0 atm

[tex]P_2[/tex] = final pressure = ?

[tex]T_1[/tex] = initial temperature = [tex]22.0^oC=273+22.0=295K[/tex]

[tex]T_2[/tex] = final temperature = [tex]180^oC=273+180=453K[/tex]

Now put all the given values in the above equation, we get:

[tex]\frac{36.0atm}{295K}=\frac{P_2}{453K}[/tex]

[tex]P_2=55.3atm[/tex]

Thus, the maximum pressure that attained in the tank will be 55.3 atm
