On a warm summer day, a large mass of air (atmospheric pressure 1:01 105 Pa) is heated by the ground to 32.0 C and then begins t
Bumek [7]

Answer:

The process is adiabatic because there no heat transfer into the system or out of the system in that there is only one system involved in this process that is air.

The temperature of the air mass when it has risen is  

   T_{final}  =  278.5 \ K  

Explanation:

From the question we are told that

      The atmospheric pressure is P_a  = 1.01 *10^{5} \ Pa

       The temperature heated to T  = 32.0^oC =  305 \ K  

       The new atmospheric pressure is  P_a__{n}}  =  8.0 * 10^{4} \ Pa

       The value of g is  g =  1.40

        The rate of cooling is  r =  \frac{1}{100}  \ ^oC/m

The adiabatic relation for this process is mathematically represented as

            P^{1- g}_{initial} T^{g}_{initial} =  P^{1-g} _{final} T^{g}_{final}

Now   P}_{initial}  =  P_ a ,   T_{initial} =  T,P _{final} =  P_a__{n}} ,  T_{final}  = ?

substituting value  

           (1.01*10^{5})^{1-1.40} * (305) ^{1.40} = (8.0*10^{4})^{1-1.40} * T_{final} ^{1.40}

          T_{final} ^{1.40}  =  2646.7

 =>    T_{final} ^{\frac{1.40}{1.40} }  =  2646.7^{(\frac{1}{1.40})}        

        T_{final}  =  278.5 \ K
