A mixture of 454 kg of applesauce at 10 degrees Celsius is heated in a heat exchanger by adding 121300 kJ. Calculate the outlet
stira [4]

Explanation:

The given data is as follows.

           Mass of apple sauce mixture = 454 kg

           Heat added (Q) = 121300 kJ

 Heat capacity (C_{p}) of apple sauce at 32.8^{o}C = 4.0177 kJ/kg^{o}C

So, Heat given by heat exchanger = heat taken by apple sauce

                            Q = mC_{p} \Delta T

or,                    Q = mC_{p} (T_{f} - T_{i})  

Putting the given values into the above formula as follows.

                     Q = mC_{p} (T_{f} - T_{i})  

              121300 kJ = 454 kg \times 4.0177 kJ/kg^{o}C \times (T_{f} - 10)

                      T_{f} = 76.5^{o}C

Thus, we can conclude that outlet temperature of the apple sauce is 76.5^{o}C.

Expliquen como prepararian una solucion homogenea y heterogenea
muminat

Una mezcla homogenea es una mezcla solida, liquida o gaseosa que tiene las mismas proporciones de sus componentes en cualquier muestra dada. A la inversa, una mezcla heterogenea tiene componentes cuyas proporciones varian a lo largo de la muestra. "Homogeneo" y "heterogeneo" no son terminos absolutos sino que dependen del contexto y del tamano de la muestra. En quimica, una suspension homogenea de material significa que cuando se divide el volumen a la mitad, la misma cantidad de material se suspende en ambas mitades de la sustancia; sin embargo, podria ser posible ver las particulas bajo un microscopio. Un ejemplo de una mezcla homogenea es el aire.
