A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 8.10kg of water at 33.9 degree
victus00 [196]

Explanation:

The given data is as follows.

        q = 69.0 kJ = 69000 J (as 1 kJ = 1000 J),

       mass (m) = 8.10 kg = 8100 g  (as 1 kg = 1000 g)

        T_{i} = 33.9^{o}C = (33.9 + 273) K = 306.9 K

         C = 4.18 J/gK

As we know that the relation between heat and change in temperature is as follows.

                   q = m \times C \times \Delta T

Putting the values into the above formula to calculate the final temperature as follows.

                  q = m \times C \times \Delta T

       69000 J = 8100 g \times 4.18 J/g K \times (T_{f} - 306.9 K)                

           69000 J = 33858 \times (T_{f} - 306.9 K)

                  (T_{f} - 306.9 K) = 2.037 K

                    T_{f} = (2.037 + 306.9) K

                                  = 308.9 K

or,                               = 309 K (approx)

Thus, we can conclude that the new temperature of the water bath is 309 K.
