Amixture of 454 kg of applesauce at 10 degrees celsius is heated in a heat exchanger by adding 121300 kj. calculate the outlet temperature of the applesauce. (hint: heat capacity for applesauce is given at 32.8 degrees celsius. assume that this is constant and use this as the average.)

Explanation:

The given data is as follows.

           Mass of apple sauce mixture = 454 kg

           Heat added (Q) = 121300 kJ

 Heat capacity () of apple sauce at = 4.0177

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

                            Q =

or,                    Q =  

Putting the given values into the above formula as follows.

                     Q =  

              121300 kJ =

                      =

Thus, we can conclude that outlet temperature of the apple sauce is .

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
