Quentin is playing baseball and is batting. He swings and hits the ball sending it flying to the outfield. Which is greater- the force of the ball on the bat or the force of the bat on the ball ?

Which accounts for an increase in the temperature of a gas that is kept a constant volume

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.
