Question

HELP PLEASE

Answer 1

Answer:

164atm

Explanation:

Given parameters:

Initial pressure  = 150atm

Initial temperature  = 27°C  = 27 + 273 = 300K

New temperature  = 55°C  = 328K

Unknown:

New pressure  = ?

Solution:

At constant volume, the pressure of a given gas varies directly with the absolute temperature.

 Mathematically;

       $\frac{P_{1} }{T_{1} }$   = $\frac{P_{2} }{T_{2} }$  

P and T are pressure and temperature values

1 and 2 are the initial and new states

  Insert the parameters and solve;

   $\frac{150}{300}$   = $\frac{P_{2} }{328}$  

     300P₂  = 150 x 328

           P₂  = 164atm
