Question

PLEASE ANSWER!

Answer 1

Answer:

0.7atm

Explanation:

Given parameters:

Initial temperature = 25.2°C  in Kelvin;  25.2 + 273  = 298.2K

Initial pressure  = 0.6atm

Final temperature  = 72.4°C in kelvin  = 72.4 + 273  = 345.4K

Unknown:

Final pressure  = ?

Solution:

Since we are dealing with pressure temperature relationships under a fixed volume, we use a simplification of the combined gas law to solve this problem.

 At fixed volume;

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

  where P and T are temperature values

              1 and 2 are the initial and final states

Input the parameters and solve for P₂

            $\frac{0.6}{298.2} = \frac{P_{2} }{345.4}$  

            P₂   = 0.7atm
