From a branch 35 m high, a 0.75 kg bird dives into a small fish tank containing
50 kg of water. What is the maximum rise in temperature of the water if the bird
gives it all of its mechanical energy?

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

From 0 to 5 seconds john pushed a box 5 meters. from 5 to 10 seconds, paul pushed the same box another 5 meters. who did more work? a. john b. paul c. john and paul did the same amount of work.

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.
