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.

What is the biological significance of the temperature at which the amylase catalyzed reaction
ipn [44]

Answer:

The biological significance is that it is the normal human body temperature and also the optimum temperature of the enzyme.

Explanation:

  • Enzymes are biological catalysts that speed up the rate of chemical reactions.
  • Enzymes catalyze specific reactions by working on a specific substrate to convert it into a product.
  • The rate of enzyme activity depends on several factors which include pH, temperature, substrate concentration, and enzyme concentration among others.
  • Enzymes work best at a specific pH and temperature known as optimum pH and optimum temperature respectively.
  • In this case, enzyme amylase works best at a temperature of 37° C which is equivalent to the normal human body temperature.
