Consider the motion of the balloon and its air contents in terms of momentum. In step 1 above, the total momentum of the balloon and its contents was zero. Recall that momentum = mv. Both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero.
Now think about what happened when the air escaped from the balloon. A certain mass of air accelerated in one direction. In order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. Use this scenario to help you explain why the soda can rotates when the water squirts out of the escape holes.
What was your hypothesis concerning the water-filled can? According to your data, do you think your hypothesis was correct? (Be sure to refer to your data when answering this question.)
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Give at least one more example of Newton's third law in everyday life.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
